[PATCH v2 10/11] riscv: dts: sophgo: add Milk-V Pioneer board device tree

[Chen Wang]

Milk-V Pioneer [1] is a developer motherboard based on SOPHON
SG2042 in a standard mATX form factor. It is a good
choice for RISC-V developers and hardware pioneers to
experience the cutting edge technology of RISC-V.

Currently only support booting into console with only uart
enabled, other features will be added soon later.
