Stuart Ianna 29ee9aacb3 arch/risc-v/common: provide architecture specific perfmon bindings.
Provides two implementations:
 - CSR_CYCLE: Cores which implement hardware performance monitoring.
 - CSR_TIME: Uses the machine time registers.

Using the up_perf_xx bindings directory is more efficient than performing a nanosecond conversion on every gettime event.
