Drivers should not be logging errors on probe deferral. Switch to using
dev_err_probe() to log failures when parsing the devicetree to avoid
errors like:

	qcom-spmi-adc-tm5 c440000.spmi:pmic@0:adc-tm@3400: get dt data failed: -517

when a channel is not yet available.

I did send a patch earlier for fixing this same issue but I did not use
dev_err_probe(). So yours is better.

Daniel, I noticed this one hasn't been picked up yet (at least it's not
in linux-next). Is this something you can do?
