Recent updates to RISC-V qemu virt platform merged today (07/14),
have enabled both pflash devices for the S-mode payload like EDK2.
These updates also aligned the design similar to other architectures
where pflash0 is for read-only code and pflash1 for variable store.
Previously only pflash1 was available for S-mode use. 

Current EDK2 will not work with this latest qemu changes since it always
assumed to boot from pflash1. So, separate the code and variable
store and use pflash0 to keep the code.

Add 'readme' about build and test as per these changes.

The changes are available in the branch :
