Subject: [PATCH v2 09/11] riscv: dts: anlogic: Add Milianke MLKPAI FS01
 board

Add support for the Milianke MLKPAI FS01 board based on the Anlogic
DR1V90 SoC. The board features 512MB of onboard memory, USB-C UART, 1GbE
RJ45 Ethernet, USB-A 2.0 port, TF card slot, and 256Mbit Quad-SPI flash.

Currently, the board can boot to a console via UART1, which is connected
to the onboard serial chip and routed to the Type-C interface.
