[PATCH v2 0/2] mconfigptr support

[Rahul Pathak]

Patches add the mconfigptr csr support. 
mconfigptr is newly incorporated in risc-v privileged architecture
specification 1.12 version. 
priv spec 1.12.0 version check is also added.


qemu-system-riscv64 -nographic -machine virt -cpu rv64,priv_spec=v1.12.0

Changelog:

v1->v2
------
1. Added privileged architecture spec version 1.12 ("v1.12.0") check
2. Added predicate function for mconfigptr which verifies
for priv spec version v1.12.0 or higher.

Thanks
Rahul
