Subject: [PATCH] thermal: qcom-spmi-adc5: Suppress probe-deferral error message

Much like 807efb7102e8 ("thermal: qcom-spmi-adc-tm5: suppress
probe-deferral error message") the ADC5 driver also spams a similar
probe-deferral error on startup when a channel is not yet available:

    [    0.343136] qcom-spmi-adc-tm5 1c40000.spmi:pmic@0:adc-tm@...0: get dt data failed: -517

Suppress it by using dev_err_probe instead, which also takes care of
storing the message as reason for deferring.
