Subject: OvmfPkg/RiscVVirt: Override for RISC-V CPU Features

This PCD provides a way for platform to override any
HW features that are default enabled by previous stages
of FW (like OpenSBI). For the case where previous/prev
stage has disabled the feature, this override is not
useful and its usage should be avoided.
