Reset itself into "relative mode."

[dhnguyen92]

Sometimes, my trackpad has spontaneously reset itself into "relative mode.", which leads to endlessly console spam, and can make system auto restart.
"kernel[0]: ApplePS2SynapticsTouchPad: Unexpected byte0 data (c0) from PS/2 controller"

A trackpad restart by using the trackpad on/off key solves this problem for a short time, while an EC reset can fix this for longer period.

@dhnguyen92 Were you able to fix the issue ? It's the only issue plaguing my setup. EC reset doesn't help. My issue is here - #87
