[PATCH 4/4] drm/msm/dpu: add source split order op for DPU 13.x

[Mahadevan P <mahadevan.p@oss.qualcomm.com>]

DPU 13.x places the SSPP op-mode register in separate REC0 and REC1
banks. Add the source split order operation for this layout, using
the shared helper to update SRC_SPLIT_ORDER in the selected bank.
