dt-bindings: arm: bcm: raspberrypi,bcm2835-firmware: Add gpio child node
Unlike the other child nodes of the raspberrypi,bcm2835-firmware device,
the gpio child is documented in a legacy text-based binding in
gpio/raspberrypi,firmware-gpio.txt. This causes DT validation failures:
arch/arm64/boot/dts/broadcom/bcm2711-rpi-4-b.dtb: 'gpio' does not match any of the regexes: 'pinctrl-[0-9]+'
from schema $id: http://devicetree.org/schemas/arm/bcm/raspberrypi,bcm2835-firmware.yaml#
Convert the binding to YAML and move it to
raspberrypi,bcm2835-firmware.yaml.
