sunxi: Add Libre Computer Board ALL-H3-CC H5 ver.

This patch adds a device tree file for the H5 version of the Libre
Computer Board ALL-H3-CC. It is the same board first introduced in
commit afe27544

 ("sunxi: Add support for Libre Computer Board
ALL-H3-CC H3 ver."), with the H3 SoC replaced with the H5 SoC, and
has 4Gb DDR3 chips instead of 2Gb ones.

The device tree utilizes the common board design file for ALL-H3-CC,
providing just the model strings and SoC specifics.
