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.
