[U-Boot] [PATCH_v2 1/2] mips: xilfpga: Add device tree files

[Zubair Lutfullah Kakakhel]

Mostly the same as the Kernel upstream device tree file except for

- alias for the serial console node
- ethernet node as the ethernet stuff isn't upstream on kernel.org yet
- uart clock-frequency passed directly in the node

V1 -> V2

Added Reviewed-by: Daniel Schwierzeck <daniel.schwierzeck at gmail.com>

Reorded patches so that DT files go before platform Kconfig for bisectibility
