Invalid CSR read for CSR=0x3b0 detected in BlackParrot cosimulation #5

In BlackParrot testing with Dromajo cosimulation, at least one test reports out an invalid CSR read for the CSR with address 0x3b0 due to it being unimplemented in the processor.

Reproduce: checkout https://github.com/black-parrot/black-parrot/commit/111bac29371ecf661e1df8f0c3d66a7141fc2398 (dev branch) cd bp_top/syn make build.v sim.v CFG=e_bp_single_core_cfg SUITE=riscv_tests PROG=rv64ui-p-fence_i COSIM_P=1

I think we discussed this offline, but for anyone curious: This is because we don't implement PMPs
