Add device tree support for usb controllers on x86

[galak]

For boards like arduino_101, quark_se_c1000_devboard, tinytile we need to add dts support similar to what we have on stm32

@SavinayDharmappa please take a look at this as well.

This would let us remove include <board.h> in subsys/usb/usb_device.c as its just need to get GPIO info, which we'd get from DT instead. This is one of the few <board.h> references left to remove.
