[PATCH v4 12/20] regulator: s2mps11: use dev_err_probe() where appropriate

["André Draszik" <andre.draszik@linaro.org>]

dev_err_probe() exists to simplify code and harmonise error messages,
there's no reason not to use it here.

While at it, harmonise some error messages to add regulator name and ID
like in other messages in this driver, and update messages to be more
similar to other child-drivers of this PMIC (e.g. RTC).
