Subject: [RFC PATCH v1 05/12] drm/bridge: remove conditionals around devicetree pointers

Remove ifdef CONFIG_OF around the drm_bridge::of_node field. This follow
the correponding change to struct device we had since 2.6.39. Having
conditional around the of_node pointers turns out to make driver code
use ugly #ifdef blocks. Drop the conditionals and remove the #ifdef
blocks from the affected drivers.
