ARM: dts: bcm283x: Drop unneeded properties in the bcm2835-firmware node

The firmware node contains a "dma-ranges" property to enable usage of
the DMA mapping API with its child devices, along with "#address-cells"
and "#size-cells" properties to support the dma-ranges. This was needed
due to usage of the incorrect device to perform the DMA mapping in
drivers. Now that this has been fixed, drop the properties.

This effectively reverts commits be08d278eb09 ("ARM: dts: bcm283x: Add
cells encoding format to firmware bus") and 55c7c0621078 ("ARM: dts:
bcm283x: Fix vc4's firmware bus DMA limitations").
