regulator: kryo-regulator: disregard M3 LPM counters in notifier path

LPM entry/exit notification for M4M is broken. The Kryo regulator driver
attempts to guarantee correctness by maintaining cached copies of M4M
entry/exit count, but under some circumstances a spurious exit notification
is received without first receiving an M3 entry notification. Remove this
safeguard check until the problem is root caused.
