RISC-V: Add Ssccfg/Smcdeleg ISA extension definition and parsing
Smcdeleg extension allows the M-mode to delegate selected counters
to S-mode so that it can access those counters and correpsonding
hpmevent CSRs without M-mode.
Ssccfg (‘Ss’ for Privileged architecture and Supervisor-level
extension, ‘ccfg’ for Counter Configuration) provides access to
delegated counters and new supervisor-level state.
This patch just enables these definitions and enable parsing.
