The board is the same as A20-OLinuXino-LIME with added eMMC chip. So the
dts is almost identical with A20-OLinuXino-LIME2.

This patch series adds a new dts file and appends the bindings
documentation.

There is new version of A20-OLinuXino-LIME with eMMC storage. The
card routing is the same as in A20-OLinuXino-LIME2-eMMC, so this
is basically copy/paste.
