Revert "drm/mipi-dsi: Set the fwnode for mipi_dsi_device"

This reverts commit 22b8ac608a which is
commit a26cc29343 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.
