Not all ports have 16 pins available.
This is one of the differences between different RZ/A1 SoC versions
(RZ/A1H, RZ/A1L etc)

I'll change the number of pins to the actual available ones on each port
for r7s72100 (RZ/A1H)

But wait, what if someone wants to use a RZ/A1L???

I don't want to make a separate dtsi file for RZ/A1L.

Is it possible to change the number of port pins in the board dts file?
For example:
  RZ/A1H: P5_0 - P5_10
  RZ/A1L: P5_0 - P5_16

So, in a rza1l-board.dts file I would put:

&port5 {
	gpio-ranges = <&pinctrl 0 80 16>;
}

Will this work?
