Subject: [PATCH] regulator: pwm-regulator: Make use of the helper function dev_err_probe()

devm_regulator_register can return -EPROBE_DEFER if the
regulator is not ready yet. Use dev_err_probe() for
pwm regulator resources to indicate the deferral reason
when waiting for the resource to come up.

Fixes: 0cd71b9a43ad ("regulator: pwm: Don't warn on probe deferral")
