imx8: add xhci driver for the soc

Browse source 
This is mostly a copy of port/usbxhci.c with PCIWADDR() replaced
by PADDR() and the pci specific code stripped out.

This could be refactored at a later time.

There is a gpio line for the main hub reset that needs to be
asserted and some power management functions that are currently
done by u-boot (using "usb start" command).

We will do these ourselfs once we have the infrastructure for
it in place.
