[PATCH 08/12] riscv: dts: sophgo: add Milk-V Pioneer board device tree

[Wang Chen]

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.

Drop, there is no such node. Otherwise, please point me where are the
bindings for it?

Anyway your submissions is incomplete. Your DTS should enable some
peripherals, like serials etc.
