USB: otg: twl4030 transceiver driver

Add driver for the high speed USB-OTG transceiver in TI's TWL4030
family of chips.

Given this and various other pending patches, OMAP3 hardware like
that from beagleboard.org, gumstix.com (Overo), and openpandora.org
should now have basic USB host and peripheral connectivity with
mainline kernels.  Ditto for less widely-available boards.
