Subject: [PATCH v6 02/10] drm/bridge: Set firmware node of drm_bridge instances automatically
Normally, the drm_bridge::of_node won't be used by bridge driver instances
themselves. Rather, it is mainly used by other modules to find associated
drm bridge drvier. Therefore, adding a drm bridge to the global bridge list
and setting 'of_node' field of a drm bridge share the same goal. Both are
for finding purpose, therefore better to group them to one function.
Update the drm_bridge_add() interface and implementation to achieve such
goal atomically, new implementation will fetch the device node from the
backing device of the drm bridge driver automatically. For the majority
cases, which is one device backing one drm bridge driver, this model works
well. Drivers still can set it manually by passing NULL if this model
doesn't fit.
While at it, Add a 'struct device *' pointer to the drm_bridge structure.
As it already being passed in by both of drm_bridge_add() and
devm_drm_bridge_add(). A lot of driver instances has already added it into
their derived structure, promote it into drm_bridge core helps to reduce
a batch of boilerplates.
