Remove the handling of the fw_cfg DT node from VirtFdtDxe now that the
fw_cfg client library has been moved to the FDT client protocol, and no
longer relies on VirtFdtDxe to pass this information via dynamic PCDs.
Since the PCDs in question are now no longer used, remove them from the
various DEC and DSC files as well.

The detection of the PSCI method has been moved to the EfiResetSystemLib
implementation, so drop the handling from VirtFdtDxe. Since no users
remain of gArmVirtTokenSpaceGuid.PcdArmPsciMethod, remove that as well.

Now that we moved the GIC discovery to our ArmGicArchLib implementation,
we can remove it from VirtFdtDxe, since it is no longer used. Remove the
PcdArmGicRevision declaration and definitions as well: VirtFdtDxe no longer
sets it, and no other drivers consume its value.

This introduces the FdtClientProtocol, which will be used to expose the
device tree provided by the host to other DXE drivers.

The arm64 kernel is hardwired to prefer DT over ACPI, unless 'acpi=force'
is passed on the kernel command line. The only other way to force the
kernel to use ACPI is not to pass an FDT to it in the first place. So
introduce a PCD that inhibits the installation of the QEMU supplied FDT
as a configuration table.

A DMA-like transfer interface has recently been implemented in QEMU for
fw-cfg. For ARM and AARCH64 virtual machines, the binding prescribes a new
8-byte wide register at offset 0x10 in the register block. Make VirtFdtDxe
expose this register if it is present.
Please see "docs/specs/fw_cfg.txt" in the QEMU tree for more information.

In order to allow a ArmGicArchLib to be implemented that returns
the supported GIC revision based on the device tree, add handling
to VirtFdtDxe to record the GIC revision at DT parsing time.

Add a fixed pointer PCD to allow build-time selection of VT100 or TTY terminal
type. The default remains VT100 emulation.
Add support for building the ARM QEMU platforms with the TTY terminal
with the "-D TTY_TERMINAL" build option.
