Remove support for the
Smcntrpmf(counter privilege mode filtering) RISC-V ISA extension.This ISA extension is quite handy for rich / supervisor-mode OS setups. But for embedded m/u-mode system it does not make much sense. Hence, this extension is removed (until we finally have S-mode support some day).
However, counter privilege mode filtering can still be emulated using the
mcounterenandmcountinhibitCSRs.
