[PATCH v6 09/10] drm/bridge: sii9234: Use fwnode APIs to abstract DT dependent API away

[Sui Jingfeng <sui.jingfeng@linux.dev>]

Switch to use the freshly created drm_bridge_set_node() helper, no
functional changes. The reason behind of this introduction is that
the name 'of_node' itself has a smell of DT dependent, and it is a
internal memeber, when there has helper function, we should use the
revelant helper and avoid directly referencing and/or dereferencing
it.
