Now the power off and power on are done in omap_usb_power_off and omap_usb_power_on respectively. However using the old USB PHY library cannot be completely removed because OTG is intertwined with PHY and moving to the new framework will break OTG. Once we have a separate OTG state machine, we can get rid of the USB PHY library.
