riscv: dts: sophgo: Add Milk-V Duo 256M board support

Browse source

The Milk-V Duo 256M is a small form factor development board based on
the Sophgo SG2002 SoC.

This patch adds basic device tree support for the board, including:
- UART console
- SD/MMC controller
- USB host
- Onboard blue status LED (connected to PWR_GPIO[2] / porte 2)

Tested on actual Milk-V Duo 256M hardware, verified boot to shell and
heartbeat LED functionality.
