Wire up the various existing pieces so that we can implemented 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, so this is added to the existing implementation of PlatformPeiLib. The associated QEMU changes are under development in Linaro, and will be sent out for review to the appropriate mailing list shortly.
