msm: mdss: Program phase factors for QSEED in Dual display mode

When scaling is involved during video playback for dual display
high resolution panels, the scaling factors such as phase step and
initial phase need to be programmed to avoid mismatched textures
and hardware hangs. Also, software pixel extension needs to be
enabled. The data is received from user module through OVERLAY_SET.
This feature is only enabled for YUV formats in VIG pipes.
