[U-Boot] [PATCH v3 7/7] sunxi: H6: Add basic Eachlink H6 Mini support

[Andre Przywara]

The Eachlink H6 Mini is a modestly priced TV box, using the Allwinner H6
SoC. It comes with 3GB of DRAM and 32GB of eMMC in the typical TV box
enclosure.

This adds a basic device tree and defconfig for it.

It contrast to the other supported H6 boards the H6 Mini uses DDR3 DRAM
chips (not LPDDR3), which require a different DRAM controller setup.
