mfd: Fixed gpio polarity of omap-usb gpio USB-phy reset 



With commit 19403165 a main part of ehci-omap.c moved to
drivers/mfd/omap-usb-host.c created by commit 17cdd29d.
Due to this reorganisation the polarity used to reset the
external USB phy changed and USB host doesn't recognize
any devices.
