From: Conor Dooley <conor.dooley@microchip.com>

The k210 devicetrees warn about missing/empty reg and/or ranges
properties:
arch/riscv/boot/dts/canaan/k210.dtsi:408.22-460.5: Warning (unit_address_vs_reg): /soc/bus@52000000: node has a unit name, but no reg or ranges property
arch/riscv/boot/dts/canaan/k210.dtsi:352.22-406.5: Warning (simple_bus_reg): /soc/bus@50400000: missing or empty reg/ranges property

Add a ranges properties that naively caps the buses after the
allocation of their last devices.
