Generic pmpcfg octet.
A PMP entry is configured through pmpaddrX and pmpcfgX CSRs, where a
single pmpcfgX CSRs holds multiple octets, each affecting the access
permission, addressing mode and “lock” attributes of a single pmpaddrX
CSR. This bitfield definition represents a single, u8-backed pmpcfg
octet affecting a single pmpaddr entry.
