lib: sbi_pmu: PMU raw event v2 support

Browse Source 
As per the updated ISA specification and SBI PMU v3.0, lower 56
bits are available for the platform to implement mhpmeventX
encoding. Implement the PMU raw event V2 support defined in SBI
v3.0 which allows more bits for platforms to encode the raw events.
