RFC usb: musb: add driver for control module

Added a new driver for the usb part of control module. This has an API to power on the USB2 phy and an API to write to the mailbox depending on whether MUSB has to act in host mode or in device mode.

Writing to control module registers for doing the above task which was previously done in omap glue and in omap-usb2 phy is removed.

Also added the dt data to get MUSB working in OMAP platforms. This series has patches for both drivers and ARCH folders, so If it has to be split I'll do it.

This series was developed on
git://git.kernel.org/pub/scm/linux/kernel/git/balbi/usb.git xceiv

Did basic enumeration testing in omap4 beagle, omap4 sdp and omap3 beagle.
