RISC-V SBI v0.3 specification defined a PMU extension to configure/start/stop the hardware/firmware pmu events. Implement PMU support in OpenSBI library. The implementation is agnostic of event to counter mapping & mhpmevent value configuration. That means, it expects platform hooks will be used to set up the mapping and provide the mhpmevent value at runtime.
