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

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).
