Subject: [PATCH] thermal: qcom-spmi-adc-tm5: suppress probe-deferral error message

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@...0: get dt data failed: -517

when a channel is not yet available.
