Subject: [PATCH] uas: ignore UAS for Norelsys NS1068(X) chips
The UAS mode of Norelsys NS1068(X) is reported to fail to work on
several platforms with the following error message:
xhci-hcd xhci-hcd.0.auto: ERROR Transfer event for unknown stream ring slot 1 ep 8
xhci-hcd xhci-hcd.0.auto: @00000000bf04a400 00000000 00000000 1b000000 01098001
And when trying to mount a partition on the disk the disk will
disconnect from the USB controller, then after re-connecting the device
will be offlined and not working at all.
Falling back to USB mass storage can solve this problem, so ignore UAS
function of this chip.

The NS1066 chip from the same vendor seems to also suffer from this
problem (its USB ID is 2537:1066) according to the report of Armbian
community. However I don't have such device (I have a USB HDD enclosure
with USB ID 2537:1066, but it doesn't report UAS function at all; as
it's
