[PATCH 1/2] regulator: dt-bindings: gpio-regulator: Fix {gpios-,}states limits

[Geert Uytterhoeven]

make dtbs_check:

    arch/arm64/boot/dts/renesas/r8a77951-salvator-xs.dtb: regulator-vccq-sdhi0: Unevaluated properties are not allowed ('gpios-states', 'states' were unexpected)
	    from schema $id: http://devicetree.org/schemas/regulator/gpio-regulator.yaml#

The number of items in "gpios-states" must match the number of items in
"gpios", so their limits should be identical.

The number of items in "states" must lie within the range from zero up
to 2^{number of gpios}.

The second issue did not cause any dtbs_check errors?
