[PATCH V2] regulator: anatop: Lower error message level for -EPROBE_DEFER

[Anson Huang]

devm_regulator_register() could return -EPROBE_DEFER when trying to
get init data and NOT all resources are available at that time, for
this case, error message is better to be present for debug level ONLY.

Changes since V1:
	- lower the defer error message to debug level instead of dropping it.
