	usb: gadget: patches for v3.9 merge window

	finally getting rid of the old ->start()/->stop() methods
	in favor of the better and improved ->udc_start()/->udc_stop().

	There were surprisingly quite a few users left, but all of them
	have been converted.

	f_mass_storage removed some dead code, which is always great ;-)

	There's also a big cleanup to the gadget framework from Sebastian
	which gets us a lot closer to having only function drivers in
	kernel and move over to configfs-based binding.

	Other than these, there's the usual set of cleanups: s3c UDCs are
	moving over to devm_regulator_bulk_get() API, at91_udc removed
	an unnecessary check for work_pending() before scheduling and
	there's the removal of an unused variable from uac2_pcm_trigger().
