usb: patches for v3.13

Final conversions to configfs for mass storage, acm_ms, and
multi gadgets.

MUSB should now work out of the box on AM335x-based boards
(beagle bone white and black) with DMA thanks to Sebastian's
work.

We can now enable VERBOSE_DEBUG on builds of drivers/usb/gadget/
by selecting CONFIG_USB_GADGET_VERBOSE.

s3c-hsotg got quite a few non-critical fixes but also learned
a few new tricks (isochronous transfers, multi count support).

The Marvel USB3 Controller driver got a memory leak fix.

devm_usb_get_phy() learned not to return NULL, ever.

Other than these patches, we have the usual set of cleanups
ranging from removal of unnecessary *_set_drvdata() to using
SIMPLE_DEV_PM_OPS.
