[PATCH v3 0/3] Add 'ngpios' and 'gpio-reserved-ranges' for vf610-gpio driver

[Haibo Chen]

Not all GPIO ports have 32 pads, so add 'ngpios' property to specify
the number. This can save some memory when alloc bitmap for GPIO,
besides GPIO tools like gpioinfo will show the correct information.

Some GPIO ports even more special, e.g. GPIO7 on imx94, it only support
IO0~IO9 and IO16~IO27, so add 'gpio-reserved-ranges' property.

Changes in v3:
- switch PATCH1 and PATCH2, move the binding changes before the DTS changes, to avoid temporary DT build warnings.
- put arm64 and arm dts changes in separated patches.
- add default value for ngpios in binding doc.
- add Frank Li's reviewed by tag
- Link to v2: https://lore.kernel.org/r/20250519-gpio-dts-v2-0-b9e77173e9c5@nxp.com

Changes in v2:
- No changes for PATCH1.
- Add PATCH2 in this verson to avoid dt-binding check.
- Link to v1: https://lore.kernel.org/r/20250516-gpio-dts-v1-1-a9c3505f54c5@nxp.com
