zynqmp: pm: Move pm_client_wakeup call from pm_req_wakeup

Call to pm_client_wakeup from pm_req_wakeup prevented the PM API
call to be used to wake up non-APU processor (e.g. from higher ELs),
since it clears power down request for specified APU processor.
Move this function out of pm_client_wakeup to allow passing wake up
requests to the PMU for other processor in the system.
