riscv: dts: spacemit: add MusePi Pro board device tree

Browse Source 
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.
