ehci-omap: (mostly) cosmetic cleanups

Various cleanups to the OMAP EHCI bus glue:

 - Whitespace fixes.

 - Busy-wait loops should really have timeouts, but lacking
   that ... at least cpu_relax() in the body.

 - Debug messages should end with newlines, so they don't
   break the next message; should not embed newlines; and
   should otherwise be clean and correctly spelled.

 - The probe() method should have initialized the SBRN value,
   so the driver didn't report "USB 0.0 started".

 - The MODULE_ALIAS() was missing its "platform:" prefix;
   doing it right means the module could hotplug/coldplug.

No real functional change except for the hotplug/coldplug thing.
