msm: mdss: reduce rotator fps for high resolution 



For 4k video playback, video only expects to decode
at 30fps for current target. This means that
rotator is only expected to run at 30fps for 4k
resolutions, this change considers this for the
rotator bandwidth calculation in order to optimize
the bandwith vote.
