OvmfPkg: AcpiPlatformDxe: don't rely on unstable QEMU interface

The fw_cfg file "etc/acpi/tables" is not a stable guest interface -- QEMU
could rename it in the future, and/or introduce additional fw_cfg files
with ACPI payload. Only the higher-level "etc/table-loader" file is
considered stable, which contains a sequence of commands to assist
firmware with reading QEMU ACPI tables from the FwCfg interface.

Because edk2 provides publishing support for ACPI tables, OVMF only uses
the Allocate command to find the names of FwCfg files to read and publish
as ACPI tables.

In one of the next patches we'll start scanning all fw_cfg files that QEMU

The RSD PTR table is known to occur in the "etc/acpi/rsdp" fw_cfg file.
Since edk2 handles RSD PTR automatically, similarly to RSDT and XSDT,
let's exclude RSD PTR too from the manually installed tables.

The following call tree exposes a bug in the lifetime (ie. too late
creation) of PciIoDevice->DevicePath. The bug can be triggered when
PciBusDxe is built into OVMF, with qemu/KVM device assignment of
a PCI-express device on the default 440FX machine type.  OVMF
correctly discovers that the device is PCIe and begins probing
extended configuration space for the device.  The root bridge
has no way to access extended config space and correctly errors,
sending us into the error reporting chain seen below.  It's
possible that this error path could also be reproduced on physical
hardware when a PCI-to-PCIe bridge is present.

In English:
- CreatePciIoDevice() allocates a zeroed out PCI_IO_DEVICE structure.
- PciIoConfigRead() tries to access the (extended) config space, and
  fails.
- PciIoConfigRead() wants to report a status code (read error) for the
  device path.
- Unfortuantely, PciIoDevice->DevicePath is still NULL at that point.
- The ASSERT() in ReportStatusCodeWithDevicePath() fires.

Fix it by moving CreatePciDevicePath() into CreatePciIoDevice(),
allowing PciIoDevice->DevicePath to be initialized before we

ArmPkg/ArmLib: Drain Write Buffer before DCache maintenance operations.

Cache maintenance operations by Set/Way require that the Write Buffer
be drained before the cache is flushed.  Without that, the flush can
miss the most recent values written as they are still "pipelined".
That has unfortunate consequences, especially where code is being
copied to RAM.
The fix is to add DSB instructions before the affected operations.
