[PATCH v4 09/21] RISC-V: Add Ssccfg ISA extension definition and parsing

[Atish Patra]

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 the definitions and enable parsing.
