Samuel Holland be3ba37143 drivers/perf: riscv: Reset the counter to hpmevent mapping while starting cpus 
[ Upstream commit 7dd646cf74 ]

Currently, we stop all the counters while a new cpu is brought online.
However, the hpmevent to counter mappings are not reset. The firmware may
have some stale encoding in their mapping structure which may lead to
undesirable results. We have not encountered such scenario though.
