usb: changes for v3.14 merge window

This pull request is quite extensive, containing
105 non-merge commits. Because of that, we describe
the changes in sections below:

New drivers:
	- Keystone PHY driver and DWC3 Glue Layer
	- Aeroflex Gaisler GRUSBDC
	- Tahvo PHY driver for N770
	- JZ4740 MUSB gluer Layer
	- Broadcom PHY Driver

Important new features:
	- MUSB DSPS learned about suspend/resume
	- New quirk_ep_out_aligned_size flag added to struct usb_gadget
	- DWC3 initializes the new quirk flag so gadget drivers can use it.
	- AM335x PHY Driver learns about remote wakeup
	- Renesas USBHS now requests DMA Engine only once
	- s3c-hsotg is now re-used on Broadcom devices
	- USB PHY layer now makes sure to initialize the notifier for all
		drivers
	- omap-control learned about TI's new AM437x devices
	- few other usb gadget/function drivers learned about the new
		configfs-based binding.

Misc Fixes and Clean Ups:
	- Several sparse fixes all over the place
	- Removal of redundant of_match_ptr()
	- r-car gen2 phy now uses usb_add_phy_dev()
	- removal of DEFINE_PCI_DEVICE_TABLE() from a few drivers
	- conversion to clk_prepare/clk_unprepare on r8a66597-udc
	- some randconfig errors and build warnings were fixed
	- removal of unnecessary lock on dwc3-omap.c
