Sunil V L 37423fa344 OvmfPkg/RiscVVirt: Add support for separate code and variable store
Currently, RiscVVirtQemu supports unified code and variable store
mainly because only one pflash devices was available in qemu for
EDK2. However, this doesn't allow to map the code part as read-only.

With recent qemu enhancements, it is now possible for EDK2 to make
use of both pflash devices in RISC-V virt machine. So, add support
to create code and vars images separately. This also allows easy
firmware code updates without losing the variable store.
