[PATCH v3 13/15] riscv: dts: canaan: fix bus {ranges,reg} warnings

[Conor Dooley <mail@xxxxxxxxxxx>]

From: Conor Dooley <conor.dooley@xxxxxxxxxxxxx>

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 reg and ranges properties that naively cap the buses after the
allocation of their last devices.
