Import the dwc-hsotg (dwc2) register definitions file from the
Linux kernel. This is a copy of drivers/usb/dwc2/hw.h from the
mainline Linux kernel, the only changes being to the header, and
two instances of 'u32' changed to 'uint32_t' to allow it to
compile. Checkpatch throws a boatload of errors due to the tab
indentation, but I would rather import it as-is than reformat it.

Add basic USB PHY support as implemented in i.MX23, i.MX28, i.MX6,
and i.MX7 SoCs.
The only support really needed - at least to boot Linux - is support
for soft reset, which needs to reset various registers to their initial
value. Otherwise, just record register values.

Add code to emulate Chipidea USB IP (used in i.MX SoCs). Tested to
work against:
-usb -drive if=none,id=stick,file=usb.img,format=raw -device \
usb-storage,bus=usb-bus.0,drive=stick
