commit <3730bc6147b0> ("drm: bridge: mcde_dsi: Drop explicit bridge
remove") has removed downstream bridge as it's prior commit <3d7039e1e649>
("drm: bridge: mcde_dsi: Switch to devm_drm_of_get_bridge") added
devm_drm_of_get_bridge for looking up if child node has panel or bridge.

However commit <b089c0a9b14c> ("Revert "drm: of: Lookup if child node
has panel or bridge") has reverted panel or bridge child node lookup
from devm_drm_of_get_bridge as it breaks the non-trivial cases the
first child node might not be a panel or bridge.

So, revert this commit to switch the previous behavior of looking up
child panel or bridge.
