!1159 xhci:fix USB xhci controller issue

Merge Pull Request from: @xiao_jiang_shui 
 
When the current HiSilicon USB xhci controller formats the faulty
U disk, it will trigger a controller exception error. This will
cause errors in the control logic of the xhci controller and
driver software. In the end, all USB devices on the xhci controller
cannot be used.

By introducing a noop command operation, restore the logic of the
xhci controller and driver software, and restore all USB devices
on the xhci controller to normal.
