drm/msm/dpu: Disable scaling for unsupported scaler types

Browse Source 
Scaling is not implemented for some type of scalers (QSEED2 and RGB) but
it was unintentionally re-enabled with change below. The remaining
condition in dpu_plane_atomic_check_pipe is not enough because it only
checks for length of scaler block (which is present). This patch adds a
additional check for setup_scaler operation.
