msm_fb: display: add CONFIG_FB_MSM_NO_MDP_PIPE_CTRL

Enable CONFIG_FB_MSM_NO_MDP_PIPE_CTRL to bypass
mdp_pipe_ctrl(). This is for vsync driven screen
update mechanism.
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_fb: Display: Fix Dithering issue for rgb565 format

Using RGB888 as source format and rgb565 as destination pixel format,
will cause image corruption on the display. Fix this issue by
setting the destination format as RGB888 in MDP and DSI controller
pixel format as RGB565 for DSI specific panels.
