To enable supporting for USB offload, define "offload" in usb controller
node of device tree. "offload" value can be used to determine which type
of offload was been enabled in the SoC.

For example:

&usbdrd_dwc3 {
	...
	/* support usb offloading, 0: disabled, 1: audio */
	offload = <1>;
	...
};

This patch doesn't require this change, right?  That's only necessary
for your DT change later on, from what I can tell, so maybe it's not
needed to list this here, as the xhci core changes do not seem to
require dt at all.
