ArmVirtPkg/FdtClintDxe: Move FdtClientDxe to EmbeddedPkg This is one of the series patches to restructure the location of modules under ArmVirtPkg for RiscVVirtPkg. RiscVVirtPkg leverage FDT Client protocol to parse FDT nodes.

ArmVirtPkg/FdtClientDxe: install DT as sysconfig table in protocol notify Replace the dependency on PcdPureAcpiBoot with a Platform Has Device Tree notification callback. Move the sysconfig table installation from the entry point function to the callback.

Revert "ArmVirtPkg/FdtClientDxe: install DT configuration table at ReadyToBoot" This reverts commit 18f6d4df9ece8b91b86511bcdd1cf7da478c3627. We realized that DXE drivers that are independent of AcpiPlatformDxe (that is, independent of QEMU's ACPI generation), such as RamDiskDxe and BootGraphicsResourceTableDxe, may produce and/or manipulate ACPI tables, at driver dispatch or even at Ready To Boot. This makes it unsafe for us to check for ACPI presence in the UEFI system config table in a Ready To Boot callback, in order to decide about exposing the DT.

ArmVirtPkg/FdtClientDxe: make DT table installation !ACPI dependent Instead of having a build time switch to prevent the FDT configuration table from being installed, make this behavior dependent on whether we are passing ACPI tables to the OS. This is done by looking for the ACPI 2.0 configuration table, and only installing the FDT one if the ACPI one cannot be found.

ArmVirtPkg/FdtClientDxe: install DT configuration table at ReadyToBoot Defer FDT configuration table installation until ReadyToBoot is signaled. This allows any driver to make modifications in the mean time, and will also allow us to defer the decision of whether to install it in the first place to later on in the boot.

ArmVirtPkg/VirtFdtDxe: move FDT config table installation to FdtClientDxe Now that FdtClientDxe is the core driver that takes ownership of the host supplied FDT, it makes sense to put it in charge of installing the FDT configuration table as well.
