With runtime_pm in place there is no longer need to turn the phy on/off in OTG layer on cable connect/disconnect, OMAP glue does this through otg.set_suspend() callback after it's called through omap_musb_mailbox() on VBUS/ID interrupt. Not doing this will save power when cable is connected but no gadget driver is loaded. This will also have side effect of automatic USB charging no longer working without twl4030_charger driver, because a regulator needed for charging will no longer be enabled, so be sure to enable charger driver if charging is needed.
