Subject: [PATCH v3 1/9] soc: qcom: rpmpd: fixup rpmpd set performance state

Remoteproc q6v5-mss does set_performace_state with INT_MAX on
rpmpd. This is currently ignored since it is greater than the
max supported state. Fixup rpmpd state to max if the required
state is greater than all the supported states.

Fixes: 075d3db8d10d ("Add support for the .set_performace_state() and
.opp_to_performance_state()")
