[PATCH] USB: gadget driver section fixups

This adds __init section annotations to gadget driver bind() routines to
remove calls from .text into .init sections (for endpoint autoconfig).
Likewise it adds __exit section annotations to their unbind() routines.

The specification of the gadget driver register/unregister functions is
updated to explicitly allow use of those sections.
