Merge tag 'drm-msm-fixes-2023-11-21' of https://gitlab.freedesktop.org/drm/msm into drm-fixes

Fixes for v6.7-rc3:

- Fix the VREG_CTRL_1 for 4nm CPHY to match downstream
- Remove duplicate call to drm_kms_helper_poll_init() in msm_drm_init()
- Fix the safe_lut_tbl[] for sc8280xp to match downstream
- Don't attach the drm_dp_set_subconnector_property() for eDP
- Fix to attach drm_dp_set_subconnector_property() for DP. Otherwise
  there is a bootup crash on multiple targets
- Remove unnecessary NULL check left behind during cleanup
