[PATCH 3.16 198/328] USB: Add quirk to support DJI CineSSD

From: Tim Anderson <tsa@biglakesoftware.com>

commit f45681f9becaa65111ed0a691ccf080a0cd5feb8 upstream.

This device does not correctly handle the LPM operations.

Also, the device cannot handle ATA pass-through commands
and locks up when attempted while running in super speed.

This patch adds the equivalent quirk logic as found in uas.
