e5778689a9 platform/x86: GPD pocket fan: Stop work on suspend 
Stop the work on suspend, otherwise it may run between our suspend method
running and the system suspending, possibly restarting the fan which
we've just stopped.

Note we already requeue the work on resume, so that we get a fresh speed
at resume.

Newer versions of the GPD pocket BIOS set the fan-speed to 2 when a
charger gets plugged in while the device is off. Mirror this in our
fan driver and use a minimum speed of 2 while charging,
