[PATCH_V2 33/34] MIPS: initial MIPS Creator CI20 board support

[Zubair Lutfullah Kakakhel <Zubair.Kakakhel@imgtec.com>]

From: Paul Burton <paul.burton@imgtec.com>

Add a device tree for the Ingenic jz4780 based MIPS Creator CI20 board.
Note that this is unselectable via Kconfig until the jz4780 SoC is made
selectable in a later commit.
