[PATCH 1/2] target/riscv: Fixup MSECCFG minimum priv check

[Alistair Francis]

From: Alistair Francis <alistair.francis@wdc.com>

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.

1: https://ibex-core.readthedocs.io/en/latest/01_overview/compliance.html

Fixes: a4b2fa433125af0305b0695d7f8dda61db3364b0 target/riscv: Introduce 
privilege version field in the CSR ops.
