msm: mdss: reduce the bandwidth request calls by mdp3



Currently mdp3 is calling bus calls for bandwidth request
as soon as there is any change in new bandwidth value.
This extra communication is showing power issues.
Do not change the bw vote for solid fill case so that
this fluctuation is avoided.
