USB: ehci minor SOC bus glue fixes

Various minor fixes to some SOC bus glue for EHCI:

 - Remove a bogus copyright (by "me"!) which someone added to the FSL
   driver, and an irrelevant comment.

 - Un-break MODULE_ALIAS() directives after platform_bus hotplugging
   acquired a backwards-incompatible change.  (Which didn't fix ANY
   of the in-tree drivers it prevented from hotplugging -- sigh.)

 - Remove some bogus assignments of platform_bus_type; that's done by
   the platform_bus code.

 - Add some FIXMEs for drivers with that pointless two-level idiom for
   probe() and remove() routines.  ("Obfuscation" is a non-goal.)
   That should help avoid future bus glue which copies that idiom.
