Subject: [PATCH] drm/msm/dpu: remove DPU_CTL_SPLIT_DISPLAY from SAR2130P
 CTL blocks

From: Dmitry Baryshkov <lumag@...nel.org>

Follow the changes in the commit a2649952f66e ("drm/msm/dpu: remove
DPU_CTL_SPLIT_DISPLAY from CTL blocks on DPU >= 5.0") and remove
DPU_CTL_SPLIT_DISPLAY from the CTL blocks on the SAR2130P platform.
Single CTL is used for all interfaces used by a single path

Fixes: 178575173472 ("drm/msm/dpu: add catalog entry for SAR2130P")
