RISC-V: Remove the current perf implementation
The current perf implementation in RISC-V is not very useful as it can not
count any events other than cycle/instructions. Moreover, perf record
can not be used or the events can not be started or stopped.
Remove the implementation now for a better platform driver in future
that will implement most of the missing functionality.
