Subject: [PATCH] drm/mcde: dsi: Add of_node_put() before return

Fix following coccicheck warning:

./drivers/gpu/drm/mcde/mcde_dsi.c:1104:1-33: WARNING: Function
for_each_available_child_of_node should have of_node_put() before return

Early exits from for_each_available_child_of_node should decrement the
node reference counter.
