msm: kgsl: Add an input handler to power up the GPU on a
 touch event

On a device where the primary input is a touchscreen nobody is
surprised that touch events are often the catalyst for drawing
frames. If the GPU is in slumber we can get a jump on the action
by watching for touch events and turning the GPU on in anticipation
of a draw call. Register for events from all input drivers
returning EV_ABS events and queue a work task to power up the GPU
if it is currently in slumber.
