usb: patches for v3.10 merge window

Here is the big Gadget & PHY pull request. Many of us have
been really busy lately getting multiple drivers to a better
position.

Since this pull request is so large, I will divide it in sections
so it's easier to grasp what's included.

- cleanups:
	. UDC drivers no longer touch gadget->dev, that's now udc-core
		responsibility
	. Many more UDC drivers converted to usb_gadget_map/unmap_request()
	. UDC drivers no longer initialize DMA-related fields from gadget's
		device structure
	. UDC drivers don't touch gadget.dev.driver directly
	. UDC drivers don't assign gadget.dev.release directly
	. Removal of some unused DMA_ADDR_INVALID
	. Introduction of CONFIG_USB_PHY
	. All phy drivers have been moved to drivers/usb/phy and renamed to
		a common naming scheme
	. Fix PHY layer so it never returns a NULL pointer, also fix all
		callers to avoid using IS_ERR_OR_NULL()
	. Sparse fixes all over the place
	. drivers/usb/otg/ has been deleted
	. Marvel drivers (mv_udc, ehci-mv, mv_otg and mv_u3d) improved clock
		usage

- new features:
	. UDC core now provides a generic way for tracking and reporting
		UDC's state (not attached, resuming, suspended, addressed,
		default, etc)
	. twl4030-usb learned that it shouldn't be enabled during init
	. Full DT support for DWC3 has been implemented
	. ab8500-usb learned about pinctrl framework
	. nop PHY learned about DeviceTree and regulators
	. DWC3 learned about suspend/resume
	. DWC3 can now be compiled in host-only and gadget-only (as well as
		DRD) configurations
	. UVC now enables streaming endpoint based on negotiated speed
	. isp1301 now implements the PHY API properly
	. configfs-based interface for gadget drivers which will lead to
		the removal of all code which just combines functions together
		to build functional gadget drivers.
	. f_serial and f_obex were converted to new configfs interface while
		maintaining old interface around.

- non-critical fixes:
	. UVC gadget driver got fixes for Endpoint usage and stream calculation
	. ab8500-usb fixed unbalanced clock and regulator API usage
	. twl4030-usb got a fix for when OMAP3 is booted with cable connected
	. fusb300_udc got a fix for DMA usage
	. UVC got fixes for two assertions of the USB Video Class Compliance
		specification revision 1.1
	. build warning issues caused by recent addition of __must_check to
		regulator API

These are all changes which deserve a mention, all other changes are related
to these one or minor spelling fixes and other similar tasks.
