[PATCH v2] drivers/perf: RISC-V: Allow programming custom firmware events

[Mayuresh Chitale]

Applications need to be able to program the SBI implementation specific
or custom firmware events in addition to the standard firmware events.
Remove a check in the driver that prohibits the programming of the custom
firmware events.
