[PATCH] target/riscv: Support Supm and Sspm as part of Zjpm v1.0

[baturo . alexey]

From: Alexey Baturo <baturo.alexey@gmail.com>

The Zjpm v1.0 spec states there should be Supm and Sspm extensions that are 
used in profile specification.
Enabling Supm extension enables both Ssnpm and Smnpm, while Sspm enables only 
Smnpm.
