msm_fb: display: empty pending queue during suspend

Overlay_play() adds a pipe into pending queue and pan_display()
will commit those pipes to hardware and empty queue. This patch
will make sure queue is empty at suspend so that no unexpected
pipes will be commited to hardware by pan_display() at resume.
Otherwise, iommu page fault may happen.

msm: ion: Only return Ion flags in ion_handle_get_flags

Since the ion_buffer.flags field is shared between the actual Ion
flags as well as the Ion heap mask, make sure that we're only
returning flags. The heap_mask bits should be masked off.

video: msm: Handle MDP_REV_43 MDP identity

Earlier code improperly labeled MSM8960v3 devices as MDP_REV_42. When this
bug is fixed the devices fails to boot. Update checks that exclusively
check against MDP_REV_42 to allow MDP_REV_42 and greater.

msm_fb: Increase backlight granularity from 15 to 255 levels

Currently number of backlight levels are set to 15, which causes
noticeable flicker when backlight level is changed from CABL
functionality in userspace. So to improve visual performance,
increase backlight granularity from current 15 levels to 255 levels.

This change is for msm8960 & apq8064 liquids which use Chimei panels.

was in progress, the pointer was not cleared, causing the next histogram
