USB: PS3: USB system-bus rework 

USB HCD glue updates to reflect the new PS3 unifed device support.
 - Fixed remove() routine.
 - Added shutdown() routine.
 - Added request_mem_region() call.
 - Fixed MODULE_ALIAS().
 - Made a proper fix for the hack done to support muti-platform in commit
   48fda45120.
