Move Smbios measurement from TCG driver to Smbios driver.
This is patch to remove smbios measurement in TCG driver. There will be other patch to add it in Smbios driver.
The problem of current SMBIOS measurement is:
1) TCG drivers do not support SMBIOS3.0 table.
2) TCG drivers do not follow TCG platform spec on: "Platform configuration information that is automatically updated,
such as clock registers, and system unique information, such as asset numbers or serial numbers,
MUST NOT be measured into PCR [1], or any other PCR."
So we decide to move Smbios measurement from TCG drivers to Smbios driver.

UefiCpuPkg: PiSmmCpuDxeSmm: Remove unused references to SmmLib
The PiSmmCpuDxeSmm module does not use any services from the SmmLib.
This change removes the SmmLib from PiSmmCpuDxeSmm module and also
removes the lib mapping in the UefiCpuPkg DSC file because no other
modules in the UefiCpuPkg use the SmmLib.
Removal of SmmLib is now possible because the only API call to it,
ClearSmi(), was ultimately removed from PiSmmCpuDxeSmm -- see the
"BUGBUG" comment in git commit 529a5a86.

OvmfPkg: QemuFlashFvbServicesRuntimeDxe: clean up includes and libraries
Before introducing the SMM driver interface, clean up #include directives
and [LibraryClasses] by:
- removing what's not directly used (HobLib and UefiLib),
- adding what's used but not spelled out (DevicePathLib),
- sorting the result.
This helps with seeing each source file's dependencies and with
determining the library classes for the SMM driver.

OvmfPkg: QemuFlashFvbServicesRuntimeDxe: split out runtime DXE specifics
In preparation for introducing an SMM interface to this driver, move the
following traits to separate files, so that we can replace them in the new
SMM INF file:
- Protocol installations. The SMM driver will install protocol interfaces
in the SMM protocol database, using SMM services.
- Virtual address change handler and pointer conversions. SMM drivers run
with physical mappings and pointers must not be converted.
There are further restrictions and changes for an SMM driver, but the rest
of the code either complies with those already, or will handle the changes
transparently. For example:
- SMM drivers have access to both UEFI and SMM protocols in their entry
points (see the PI spec 1.4, "1.7 SMM Driver Initialization"),
- MemoryAllocationLib has an SMM instance that serves allocation requests
with the gSmst->SmmAllocatePool() service transparently, allocating
runtime-marked SMRAM.
In every case, the entry at subscript zero is meant as "physical address",
while the entry at subscript one is meant as "virtual address" -- a
pointer to the same object. The virtual address entry is originally
initialized to the physical address, and then it is converted to the
virtual mapping in FvbVirtualddressChangeEvent().
Functions that (a) read the listed fields and (b) run both before and
after the virtual address change event -- since this is a runtime DXE
driver -- derive the correct array subscript by calling the
EfiGoneVirtual() function from UefiRuntimeLib.
The problem with the above infrastructure is that it's entirely
superfluous.
EfiGoneVirtual() "knows" whether EFI has gone virtual only because the
UefiRuntimeLib constructor registers the exact same kind of virtual
address change callback, and the callback flips a static variabe to TRUE,
and EfiGoneVirtual() queries that static variable.
In effect this means for QemuFlashFvbServicesRuntimeDxe: "when there is a
virtual address change, convert the entries with subscript one from
physical to virtual, and from then on use the entries with subscript one".
This would only make sense if QemuFlashFvbServicesRuntimeDxe ever needed
the original (physical) addresses (ie. the entries with subscript zero)
after the virtual address change, but that is not the case.
Replace the arrays with single elements. The subscript zero elements
simply disappear, and the single elements take the role of the prior
subscript one elements.

Furthermore, in "FwBlockService.c" the function comment blocks are now
indented; their original position causes diff to print bogus function

(2) The hypervisor is allowed to look at, and act upon, a live virtio ring
at any time, even without explicit virtio kicks from the guest.
Should boot loader code or kernel code, running between ExitBootServices()
and the kernel's own virtio drivers resetting the device, overwrite the
pages that used to contain the virtio ring before ExitBootServices(), QEMU
could theoretically interpret that unrelated data as garbage ring
contents, and abort the guest.
Although we have seen no such reports, better be prudent and reset the
device in an ExitBootServices() event handler. Among other things, this
causes QEMU to forget about the device's virtio ring.

MdeModulePkg: FaultTolerantWriteDxe: mellow DEBUGs about workspace reinit
The IsValidWorkSpace() function checks if the working block header of the
workspace is valid. A mismatch detected by this function is not
necessarily an error; it can happen with an as-yet unwritten flash chip,
which is e.g. common and normal when a new ArmVirtQemu virtual machine is
booted. Therefore downgrade the message emitted by IsValidWorkSpace() from
EFI_D_ERROR to EFI_D_INFO, and change the wording from "error" to
"mismatch".
The only caller of IsValidWorkSpace(), InitFtwProtocol(), handles all of
the following cases:
(1) IsValidWorkSpace() succeeds for the working block -- this is normal
operation,
(2) IsValidWorkSpace() fails for the working block, but succeeds for the
spare block -- InitFtwProtocol() then restores the working block from
the spare block,
(3) IsValidWorkSpace() fails for both the working and spare blocks --
InitFtwProtocol() reinitializes the full workspace.
In cases (2) and (3), InitFtwProtocol() logs additional messages about the
branch taken. Their current level is EFI_D_ERROR, but the messages are
arguably informative, not necessarily error reports.
Downgrade these messages from EFI_D_ERROR to EFI_D_INFO, so that they
don't clutter the debug output when the PcdDebugPrintErrorLevel mask only
enables EFI_D_ERROR (i.e., in a "silent" build).
