Besides, this also means that we don't need to add the fwnode
pointer into struct drm_bridge as member. Relief the conflicts
with other reviewers if the work of switching to fwnode is still
needed. As for majorities cases (1 to 1), of_node and fwnode can
be retrieved with 'struct device *' easily. The aux-bridge.c and
aux-hdp-bridge.c can also be converted too easily.

of_node, fwnode, swnode and device properties are all belong to
the backing device structure itself. It can be more natural to use
device_proterty_read_xxx() APIs after init time, Which in turn
avoid the need to acquire and duplicate all properties another
time in the driver private structure.

We could do the programming around the 'struct device *.', remove
a batch of boilerplate.
