usb: musb: wake the device before ulpi transfers
musb can be suspended at the time some other driver wants to do ulpi transfers using usb_phy_io_* functions, and that can cause data abort, as it happened with isp1704_charger: http://article.gmane.org/gmane.linux.kernel/1226122 Add pm_runtime to ulpi functions to rectify this. This also adds io_dev to usb_phy so that pm_runtime_* functions can be used.
