Use the generic PHY framework API to get the PHY. The usb_phy_set_resume and usb_phy_set_suspend is replaced with power_on/get_sync and power_off/put_sync to align with the new PHY framework. musb->xceiv can't be removed as of now because musb core uses xceiv.state and xceiv.otg. Once there is a separate state machine to handle otg, these can be moved out of xceiv and then we can start using the generic PHY framework.
