refactor(psci): factor common code out of the standby finisher

Browse source 
psci_suspend_to_standby_finisher and psci_cpu_suspend_finish do mostly
the same stuff, besides the system management associated with their
respective wakeup paths. So bring the wake from standby path in line
with the wake from reset path - caller acquires locks and manages
context. This way both behave in vaguely the same way. We can also bring
their names in line so it's more apparent how they are different.

This is in preparation for cores waking from sleep, coming in another
patch. No functional change is expected.
