lcdif_attach_bridge() uses dev_err_probe() in some error paths, dev_err() +
return in others. Use dev_err_probe() for all of them to make code
consistent, simpler and with bettere error reporting.

Changes in v2:
- rewrote after removal of previous patch removing loop
- not added review/test trailers as the code is a bit different
