From: Conor Dooley <conor.dooley at 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 at 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 at 50400000: missing or empty reg/ranges property
Add reg and ranges properties that naively cap the buses after the
allocation of their last devices.
