usb: patches for v3.11 merge window

All function drivers are now converted to our new configfs-based
binding. Eventually this will help us getting rid of in-kernel
gadget drivers and only keep function drivers in the kernel.

MUSB was taught that it needs to be built for host-only and
device-only modes too. We had this support long ago but it
involved a ridiculous amount of ifdefs. Now we have a much
cleaner approach.

Samsung Exynos4 platform now implements HSIC support.

We're introducing support for AB8540 and AB9540 PHYs.

MUSB module reinsertion now works as expected, before we were
getting -EBUSY being returned by the resource checks done on
driver core.

DWC3 now has minimum support for TI's AM437x series of SoCs.

OMAP5 USB3 PHY learned one extra DPLL configuration values because
that PHY is reused in TI's DRA7xx devices.

We're introducing support for Faraday fotg210 UDCs.

Last, but not least, the usual set of non-critical fixes and cleanups
ranging from usage of platform_{get,set}_drvdata to lock improvements.
