[U-Boot] [PATCH v3 05/10] drivers: usb: musb: adopt musb backend driver to driver model

Currently all backend driver ops uses hard coded physical
address, so to adopt the driver to DM, add device pointer to ops
call backs so that drivers can get physical addresses from the
usb driver priv/plat data.
