Add support for Sophgo's Milk-V Duo board, only minimal device tree and
serial console are enabled, and it can boot via vendor first stage
bootloader.

The sequence of patches seems to be wrong.
We expect that after each single patch building succeeds. But the
device-tree is neither in this patch nor in a preceding patch. Please,
swap patch 1 and 2.

Changes in v2:
- Fold the defconfig patch to first patch
- Remove unnecessary environment settings of consoledev and baudrate in

Is there a limitation on the size of the binary or why are you excluding
this option?
With the loady command you should be able to load an EFI binary via the
UART and then launch it. U-Boot comes with some EFI test applications
that you could run like smbiosdump.efi.
Best regards
