msm: camera: Avoid memory corruption by changing order of enum

SET_POSITION is added above MOVE_FOCUS which makes kernel prone to
memory corruption as MOVE_FOCUS enum is changed. when CFG_POSITION
is not present and userspace calls MOVE_FOCUS kernel misinterprets
MOVE_FOCUS as SET_POSITION and thus copies user structure to wrong
structure and makes memory to corrupt.

[media] Revert "[media] v4l2: vb2: one more fix for REQBUFS()"

This reverts commit 31901a078af29c33c736dcbf815656920e904632.

Queue should be reinitialized on each REQBUFS() call even if the memory
access method and buffer count have not been changed. The user might have
changed the format and if we go the short path introduced in that commit,
the memory buffer will not be reallocated to fit with new format.

The previous patch was just over-engineered optimization, which just
introduced a bug to videobuf2.

msm: mdss: remove interruptible timeout waits

Currently display driver contexts are not utilizing interruptible
wake-ups while using wait_for_completion_interruptible_timeout. This
can lead to incorrect context wake-up and un-predictable outcome. Since
there is already a timeout attached to these kind of context sleeps, it
is safe to replace them with wait_for_completion_timeout.

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.
