msm: mdss: update MDP QOS remapper settings for 8909 



Update MDP3 QOS remapper settings based on panel width.
As per HW design MDP3 fill level depends on panel width.
So for panels with width less than 720 pixels needs to have fill
level of 50% of what the fill level needed for panels with
width greater than equal to 720.
