The first patch extends the number of PMP regions supported up to 64,
following the RISC-V Privileged Specification (version >1.12), where
RV32 can have up to 64 PMP regions configured through 16 CSRs.

The second patch makes the PMP region count configurable via a new
CPU parameter `num-pmp-regions`. This allows platforms to adjust
the number of PMP regions without relying on a fixed default value.
If unspecified, the default remains 16 to preserve compatibility.
