mdp: mdss: Tune bandwidth and clock based on ROI

Calculate bandwidth and MDP clock requirement considering
the ROI submitted for a frame. When doing partial frame update
for smart panels, the data actually fetched for a pipe is not
always the full resolution of the buffer programmed. Use the
ROI passed to find out the region of fetching and calculate the
bandwidth and clock values accordingly.

msm: mdp3: implement overlay prepare ioctl for mdp3 driver

Implement overlay prepare ioctl call for mdp3 display driver. This will
allow a full frame with multiple overlays to be configured at once and
perform frame level checks before being pushed to display. This function
guarantees that if the call is successful, the frame can be displayed
successfully on the screen when display commit is called.

msm: mdss: Avoid GPIO warnings during boot up
During continuous splash screen handoff, we see GPIO
warnings since we try to free the GPIOs without
requesting them before. This change takes care of avoiding
these warnings.
