drm/bridge: lt9611uxc: Don't log an error when DSI host can't be found
[ Upstream commit 6d9e877cde7e9b516a9a99751b8222c87557436d ]
Given that failing to find a DSI host causes the driver to defer probe,
make use of dev_err_probe() to log the reason. This makes the defer
probe reason available and avoids alerting userspace about something
that is not necessarily an error.
