riscv: dts: spacemit: add MusePi Pro board device tree
Add initial device tree support for the MusePi Pro board [1]. The board is using the SpacemiT K1/M1 SoC. This device tree is adapted from the SpacemiT vendor tree [2] and enables basic board functionality, including UART console, LED, eMMC, Ethernet, and PDMA.
