1 is not enough for i.MX9, enlarge it.

I'm not that knowledgeable about i.MX9, but i thought vf610 was
Vybrid, which is not an i.MX9. Does i.MX9 reuse the Vybrid GPIO
controller? Is this change also valid for the Vybrid?

[Peng Fan] 

i.MX9 reuse the gpio-vf610 driver and yaml dtschema. There are some
minor differences from hardware level. The gpio-ranges will also impact
vybrid, but this may not matter.

Peng.

So maybe use a constraint to limit it to 1 for everything other than
fsl,imx93-gpio?
