[PATCH v3 0/2] Add Loongson-2K0300 processor support

[wjjsn]

The first patch adds the necessary DT binding documentation,
and the second patch adds the DTS and DTSI files for the SoC
and the board.

Changes in v3:
- Corrected the compatible string in DT bindings from 'loongson,99pi' 
  to 'loongson,ls2k0300-ref' to match the board's formal name.

Changes in v2:
- Split DT bindings and DTS into separate patches to comply with
  upstream requirements.
- Included the missing Documentation/devicetree/bindings/ modification.

Known issues:
1. The clk controller node is correctly defined, but some frequency
   configurations rely on future driver-side fixes.
2. uart0 is currently placed under the root node as the 2K0300
   manual lacks explicit documentation on the bus/interconnect 
   hierarchy (comparable to the bus@10000000 in other 2K SoCs).
