This reverts commit ac88a1f41f93499df6f50fd18ea835e6ff4f3200 which is commit a26cc2934331b57b5a7164bff344f0a2ec245fc0 upstream.
Reason for revert: 1. The commit [1] does not land on linux-5.15, so this patch does not fix anything.
2. Since the fw_devlink improvements series [2] does not land on linux-5.15, using device_set_fwnode() causes the panel to flash during bootup.
Incorrect link management may lead to incorrect device initialization, affecting firmware node links and consumer relationships. The fwnode setting of panel to the DSI device would cause a DSI initialization error without series[2], so this patch was reverted to avoid using the incomplete fw_devlink functionality.
