firmware: arm_sdei: Remove _sdei_event_unregister()

Browse Source 
_sdei_event_unregister() is called by sdei_event_unregister() and
sdei_device_freeze(). _sdei_event_unregister() covers the shared
and private events, but sdei_device_freeze() only covers the shared
events. So the logic to cover the private events isn't needed by
sdei_device_freeze().

   sdei_event_unregister        sdei_device_freeze
      _sdei_event_unregister       sdei_unregister_shared
                                     _sdei_event_unregister

This removes _sdei_event_unregister(). Its logic is moved to its
callers accordingly. This shouldn't cause any logical changes.
