usb: phy: twl4030-usb: don't enable PHY during init
There is no need to do it, otg.set_suspend(false) (which itself comes from runtime_pm OMAP glue calls) will enable it later anyway. This used to be the place where things were enabled if booted with cable connected before runtime_pm conversion, but now can be dropped.
