target/riscv: Fixup MSECCFG minimum priv check
There is nothing in the RISC-V spec that mandates version 1.12 is
required for ePMP and there is currently hardware [1] that implements
ePMP (a draft version though) with the 1.11 priv spec.

Fixes: a4b2fa433125 ("target/riscv: Introduce privilege version field in the CSR ops.")
