Add support for pinctrl-0 through pinctrl-8 explicitly instead of trying
to add support for pinctrl-%d properties.
Of all the pinctrl-* properties in dts files (20322), only 47% (9531)
are pinctrl-%d properties. Of all the pinctrl-%d properties, 99.5%
(9486) are made up of pinctrl-[0-2]. 'pinctrl-8' is the current maximum
found in dts files.
Trying to parse all pinctrl-* properties and checking for pinctrl-%d is
unnecessarily complicated. So, just add support for pinctrl-[0-8] for
now. In the unlikely event we ever exceed pinctrl-8, we can come back
and improve this.

v1->v2:
- Clarified in commit text that pinctrl-8 is the max found in the dts
files.
