Subject: [PATCH] thermal/drivers/qcom: Demote error log of thermal zone register to debug

devm_thermal_of_zone_register() can fail with -ENODEV if thermal zone for
the channel is not represented in DT. This is perfectly fine since not all
sensors needs to be used for thermal zones but only a few in real world.

So demote the error log to debug to avoid spamming users.
