msm: mdss: fix issue in calculating decimated dimensions
Width and height are not properly calculated when decimation
is involved. When there is scaling on a pipe, the required number
of pixels are wrongly programmed resulting in pipe hangs and
leading to TLB SYNC issues. This change handles proper
calculation of decimated width and height.
