The raspberrypi,bcm2835-firmware devices requires a dma-ranges property,
and, as a result, also needs to specify #address-cells and #size-cells.
Those properties have been added to thebcm2835-rpi.dtsi in commits
be08d278eb09 ("ARM: dts: bcm283x: Add cells encoding format to firmware
bus") and 55c7c0621078 ("ARM: dts: bcm283x: Fix vc4's firmware bus DMA
limitations"), but the DT bindings haven't been updated, resulting in
validation errors:
arch/arm64/boot/dts/broadcom/bcm2711-rpi-4-b.dtb: firmware: '#address-cells', '#size-cells', 'dma-ranges', 'gpio' do not match any of the regexes: 'pinctrl-[0-9]+'
from schema $id: http://devicetree.org/schemas/arm/bcm/raspberrypi,bcm2835-firmware.yaml#
Fix this by adding the properties to the bindings.
