This adds the scountinhibit CSR definition and S-mode accessible hpmevent
bits defined by smcdeleg/ssccfg. scountinhibit allows S-mode to start/stop
counters directly from S-mode without invoking SBI calls to M-mode. It is
also used to figure out the counters delegated to S-mode by the M-mode as
well.

Thanks, queued for v7.3 with the typo fixed in the subject line.
