msm: kgsl: Allow GPU start to run in a high priority queue

The GPU start sequence needs to run with low latency when coming
out of slumber for the first draw command. For those cases allow the
start function to be queued into a high priority workqueue to reduce
the chance of it getting scheduled out.

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.

msm: kgsl: Schedule adreno_start in a high priority workqueue

Better safe than sorry. Also, return early if we didn't set a _wake_timeout.

msm: kgsl: Update calculation for graphics IOMMU context IDs

Calculate graphics IOMMU context IDs using the 'label' property of
the device tree node of that context. Context IDs are independent
of the register addresses of the SMMU device and its contexts, which
change for every target.
