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