RISC-V: Add Smcntrpmf extension parsing
Smcntrpmf extension allows M-mode to enable privilege mode filtering
for cycle/instret counters. However, the cyclecfg/instretcfg CSRs are
available in Ssccfg only if Smcntrpmf is present.
That's why, kernel needs to detect presence of Smcntrpmf extension and
enable privilege mode filtering for cycle/instret counters.
