drm/bridge: lt8912b: Don't log an error when DSI host can't be found
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.
