Subject: OMAP still fails - usb phy stuff

I still see some OMAP randconfigs failing with this:

Probably caused by over-use of the damned select statement:

warning: (OMAP_USB2 && TWL4030_USB) selects USB_PHY which has unmet direct dependencies (USB_SUPPORT)
warning: (OMAP_USB2) selects OMAP_CONTROL_USB which has unmet direct dependencies (USB_SUPPORT && (ARCH_OMAP2PLUS || COMPILE_TEST))
warning: (OMAP_USB2 && TWL4030_USB) selects USB_PHY which has unmet direct dependencies (USB_SUPPORT)
warning: (OMAP_USB2) selects OMAP_CONTROL_USB which has unmet direct dependencies (USB_SUPPORT && (ARCH_OMAP2PLUS || COMPILE_TEST))

You have to wonder why OMAP_USB2 can be enabled when USB_SUPPORT is
disabled.
