[PATCH v2] drm/rockchip: dsi: Open-code drm_simple_encoder_init()

Sun Jun 7 05:37:40 PDT 2026
Simple KMS helper are deprecated since they only add an intermediate
layer between drivers and the atomic modesetting.
This patch removes the dependency on drm_simple_encoder_init from rockchip
DRM drivers by inlining this helper.
