mfd: omap: control: usb-phy: introduce the ctrl-module usb driver
Created a new platform driver for the platform device created by the
control module mfd core, wrt usb. This driver has API's to power on/off
the phy and the API's to write to musb mailbox.
(p.s. the mailbox for musb in omap4 is present in system control
module)
