With a call to drm_of_panel_bridge_remove() we could remove the bridge
without store it in ldtc internal driver structure.

65c6680d38 drm: stm: remove dead code and pointless local lut storage
The redundant fb helper .load_lut is no longer used, and can not
work right without also providing the fb helpers .gamma_set and
.gamma_get thus rendering the code in this driver suspect.

Just remove the dead code.
