[PATCH RFC] ehci-omap: simple suspend implementation

This powers down the phy and on a gta04 it reduces suspend current by 13 mA. For unknown reasons usb does not power on properly. Also calling usb_phy_shutdown() here feels wrong apparently the reset line has to be activated. usb_phy_set_suspend is not enough here. The power consumption still stays
