Hi Wesley,

It looks like I can get the transfer ring address by calling
xhci_get_xfer_resource,
and the xhci_get_ir_resource() is called to get access to the new structure
"xhci_interrupter" for the event ring address. From code review, I can
say these
APIs allow us to get the information we need.

Of course, we will integrate this patchset to verify if compatible
with our design.

Thanks,
Albert
