PM: domains: Reverse the order of performance and enabling opsqcom/pm/reverse_power_on_set_perf

Rather than enabling and then setting the performance state, which usually
translates into two different levels (voltages) in order to get to the
one required by the consumer, we could give a chance to the providers to
cache the performance state needed by the consumer and then, when powering
on the power domain, the provider could use the cached level instead.
Also the drop_performance and power_off have to be reversed so that
when the last active consumer suspends, the level doesn't actually drop
until the pd is disabled.

For the power domains that do not provide the set_performance, things
remain unchanged, as does for the power domains that only provide the
set_performance but do not provide the power_on/off.
