drm/bridge: Drop conditionals around of_node pointers 

This patch is based on commit c9e358dfc4 ("driver-core: remove
conditionals around devicetree pointers").

Having conditional around the of_node pointer of the drm_bridge
structure turns out to make driver code use ugly #ifdef blocks. Drop the
conditionals to simplify drivers. While this slightly increases the size
of struct drm_bridge on non-OF system, the number of bridges used today
and foreseen tomorrow on those systems is very low, so this shouldn't be
an issue.

So drop #if conditionals by adding struct device_node forward declaration.
