"pinctrl-single,gpio-range" allows us to define a dis-contiguous
range of pinctrl registers that can have different mux settings for
GPIO mode of operation. However, the maxItems seem to be set to 1 in
processed schema for some reason. This is incorrect. For example:
arch/arm64/boot/dts/hisilicon/hi6220.dtsi and others have more than
one dis-contiguous range.

Arbitrarily define a max 100 count to override the defaults.

I am not sure if I should call this RFC or not.. and if this is even the
right solution.. I am on 2024.05 dt-schema for this check.

I noticed this when adding gpio-ranges for am62p platform:
https://gist.github.com/nmenon/7019cd2f24be47997640df5db60a7544

It is possible that this is a bug in dt-schema, but I have'nt been able
to track it down either.

behavior seen is the following:
pinctrl-single,gpio-range = <&mcu_pmx_range 0 21 7>;
generates no warning
However,
pinctrl-single,gpio-range = <&mcu_pmx_range 0 21 7>, <&mcu_pmx_range 32 2 7>;

generates "is too long" warning.

yes, I had expected the same, but processed schema indicates a maxItems
of 1 for reasons I am unable to make sense of.. will be great to have
some additional eyes:
