Subject: uas: Add a quirk for rejecting ATA_12 and ATA_16 commands
From: Hans de Goede <hdegoede@xxxxxxxxxx>
commit 593078525c8b234a35a36ff551b8716464e86481 upstream.
And set this quirk for the Seagate Expansion Desk (0bc2:2312), as that one
seems to hang upon receiving an ATA_12 or ATA_16 command.

https://bbs.archlinux.org/viewtopic.php?id=183190
While at it also add missing documentation for the u value for usb-storage
quirks.
