[PATCHv2] regulator: pwm-regulator: Make use of the helper function dev_err_probe()

[Anand Moon]

devm_pwm_get() can return -EPROBE_DEFER if the pwm 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")
