Ard Biesheuvel 39c503f155 ArmVirtPkg: implement ArmVirtPsciResetSystemPeiLib
Implement a ArmVirtPkg specific version of the PSCI ResetSystemLib that
is usable in the PEI phase, as the existing one relies on the FDT client
protocol, making it unsuitable.

Note that accessing the device tree passed by QEMU via its initial base
address is guaranteed to be safe at any time during the PEI phase, so we
can defer discovery of the PSCI method until the time the reset library
is actually invoked (which is rarely)
