[PATCH] drm/mipi: set fwnode when a mipi_dsi_device is registered

[Will McVicker]

This allows the fw_devlink feature to work across mipi_dsi bus devices too.
This feature avoids unnecessary probe deferrals of mipi_dsi devices, defers
consumers of mipi_dsi devices till the mipi_dsi devices probe, and allows
mipi_dsi drivers to implement sync_state() callbacks.
