Subject: [PATCH v2 0/2] Add 'ngpios' and 'gpio-reserved-ranges' for
 vf610-gpio driver

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.
