[PATCH] mfd: omap-usb: depend on COMMON_CLK to fix compile tests

[Krzysztof Kozlowski]

The MFD_OMAP_USB_HOST uses Common Clock Framework thus it cannot be
built on platforms without it (e.g. compile test on MIPS with LANTIQ):

    mips-linux-ld: drivers/mfd/omap-usb-host.o: in function `usbhs_omap_probe':
    omap-usb-host.c:(.text+0x940): undefined reference to `clk_set_parent'
