usb: phy: twl4030: fix cold plug on OMAP3
Having twl4030_usb_phy_init() (detects if a cable is connected before twl4030 is probed) in twl4030 probe makes cable connect events to be missed by musb glue, since it gets loaded after twl4030. Having twl4030_usb_phy_init as a usb_phy ops lets twl4030_usb_phy_init to be called when glue is ready.
