[PATCH] rtc: pcf85063: replace dev_err+return with return dev_err_probe

[Maud Spierings via B4 Relay]

From: Maud Spierings <maudspierings@gocontroll.com>

Replace the dev_err plus return combo with return dev_err_probe() this
actually communicates the error type when it occurs and helps debugging
hardware issues.

I had some issues with a pcf85063a this change helped debugging it,
hopefully it can help someone else in the future as well.
