[SRU] [F/J/M/N] [PATCH 0/1] Fix malfunction SANDISK USB drive

[Kai-Heng Feng]

BugLink: https://bugs.launchpad.net/bugs/2040948

[Impact]
Sandisk USB drive can stop working after reboot.

[Fix]
Disable USB3 LPM at shutdown, so the device won't linger in wrong power
state at bootup.

[Test]
The affected SANDISK USB drive remains in lsusb for 10k times reboot.

[Where problems could occur]
Nothing that I can think of. This is the right thing to do.
To take a step further, the USB core should probably put USB devices to
USB U3 to save power and properly power cycle it. But let's do it when
it's proven needed.
