pinctrl: sunxi: Introduce the strict flag
Our pinctrl device should have had strict set all along. However, it wasn't the case, and most of our old device trees also have a pinctrl group in addition to the GPIOs properties, which mean that we can't really turn it on now. All our new SoCs don't have that group, so we should still enable that mode on the newer one though. In order to enable it by default, add a flag that will allow to disable that mode that should be set by pinctrl drivers that cannot be migrated.
