target/riscv/pmp.c: pmpcfg_csr_read returns bogus value on RV64
pmp_read_cfg() returns 8-bit value, which is combined together to form a single pmpcfg CSR.
The default promotion rules will result in an integer here ("i*8" is integer, which
flows through) resulting in a 32-bit signed value on most hosts.
That's bogus on RV64I, with the high bits of the CSR being wrong.
