As pinctrl handles, it may be possible the pinctrl gpio ranges
are still not got registered when user call pinctrl_gpio_request.
Thus, add defer support for it too.

I didn't look at this, because V4 was sent without this patch, so I
assumed it'd been dropped by Dong. Was I wrong?

I thought this patch had no relationship with dummy state v4 patch and
it had no changes, so i did not resend it out with the v4 patch again.
It did not mean drop. Sorry for causing confusing.
