My preferred option would be to turn the 'menuconfig PHY' into 'menu', which is what we did to solve a similar problem in drivers/mfd: It lets us 'select' specific PHY drivers without turning on the entire menu. Using 'select PHY' has the nasty side-effect of creating an incorrect dependency between the OMAP EHCI driver and all the non-OMAP phy drivers that become visible once the usb-phy directory gets enabled.
