DCSS supports 90/180/270 degree rotations for Vivante tiled and super-tiled formats. Unfortunately, with the current code, they didn't work properly. This simple patch makes the rotations work by fixing the way the scaler is set up for 90/270 degree rotations. In this particular case, the source width and height need to be swapped since DPR is sending the buffer to scaler already rotated. Also, make sure to allow full rotations for DRM_FORMAT_MOD_VIVANTE_SUPER_TILED.
