The BCM2711 supports 58 GPIOs [1] by using the existing BCM2835 GPIO registers
completely. So there is no need to change the binding.

Patch 1 and 2 prepare the pinctrl driver to be extended to 58 GPIOs in Patch
3.
I didn't want to squash them in order to make review as easy as possible.
The final patch 4 assigns all SoC GPIOs a label as we already did for
the older Raspberry Pi boards.

Overall this looks good to me (modulo the small comments). I also gave it a go
on RPi4 and RPi3b without issues.
