usb: Make sure usb/phy/of gets built-in
DWC3 driver uses of_usb_get_phy_mode() which is
implemented in drivers/usb/phy/of.c and in bare minimal
configuration it might not be pulled in kernel binary.
In case of ARC or ARM this could be easily reproduced with
"allnodefconfig" +CONFIG_USB=m +CONFIG_USB_DWC3=m.
On building all ends-up with:
---------------------->8------------------
Kernel: arch/arm/boot/Image is ready
Kernel: arch/arm/boot/zImage is ready
Building modules, stage 2.
MODPOST 5 modules
ERROR: "of_usb_get_phy_mode" [drivers/usb/dwc3/dwc3.ko] undefined!
make[1]: *** [__modpost] Error 1
make: *** [modules] Error 2
---------------------->8------------------
