Fix PMPADDR hookup to RVFI (and check/fix other similar issues if existing)

Created by: Silabs-ArjanB

For PMPADDR there is sometimes a difference in the value stored in the CSR and the value read from the CSR (as per the PMP spec). A new signal pmp_addr_n_r was introduced in the RTL to represent the 'next read value upon a write', see https://github.com/openhwgroup/cv32e40s/pull/254.

This signal is currently assigned to 0 and should be implemented (logic similar to the logic present on pmp_addr_rdata).

Similar _n_r values should be introduced for any other CSR where the value read can differ from the value actually stored.
