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

v1->v2:
- removed RELOCATABLE and HAVE_PBL_MULTI_IMAGES from Kconfig (Ahmad)
- used __dummy__.o insead of an empty file (Ahmad)
- removed include/mach/sunxi/barebox-arm.h (Ahmad)
v2->v3:
- add arch sun50i-a64 + mci driver to the multi_v8_defconfig (Sascha)
- remove the sunxi_v8_defconfig
