[PATCH 6/6] ARM: sunxi: Introduce mach-sunxi

[Jules Maselbas]

Add some boilerplate, Makefiles, Kbuild.
A generic barebox-dt-2nd.img image can be build for A64 SoC using
the sunxi_v8_defconfig.

This image can be booted from u-boot and has been tested on Pine64+,
it should work on other A64 SoC such as the pinephone, and other Pine64
boards, it might also work on H6 SoC which uses the same sd/mmc controler.
