RISC-V: Add Ssccfg extension CSR definition
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.
