[00/19] xhci features for usb-next

Hi Greg

A set of xhci features and cleanups for usb-next, including xhci dbc
cleanups, MSI rework, and fixing how we reconfigure max packet size
for xhc.

One patch fixes a null pointer deref issue, but this hasn't been seen
in real life. It's a theoretical case triggered by adding a 3 second
delay in the driver.
So I don't think it should go to stable.

Thanks
Mathias
