[PATCH v3 0/9] ArmVirtPkg: implement measured boot for ArmVirtQemu

["Ard Biesheuvel" <ard.biesheuvel@linaro.org>]

Wire up the various existing pieces so that we can implement measured
boot on ArmVirtQemu based on the TPM support in QEMU, just like it has
been implemented for x86 in OvmfPkg.

The main difference is that on ARM, we first need to discover the TPM base
address from the device tree provided by QEMU, as well as the PSCI method
used to perform a cold reset.

Changes since v2:
- add Laszlo's ack to patches #2 and #4
- add PcdTpm2SupportEnabled PCD declarations to all individual platforms in
  ArmVirtPkg, even though only ArmVirtQemu really needs it
- split patch #5 into several patches

Changes since v1:
- use a separate ResetSystemLib instance based on on-demand parsing of the
  DT, and expose it via the ResetSystem PPI to other client PEIMs
- add Laszlo's ack to #1
- incorporate Laszlo's review feedback across the board
