A64 OLinuXino board from Olimex has three variants with onboard eMMC:
A64-OLinuXino-1Ge16GW, A64-OLinuXino-1Ge4GW and A64-OLinuXino-2Ge8G-IND. In
addition, there are two variants without eMMC. One without eMMC and one with SPI
flash. This suggests the need for separate device tree for the three eMMC
variants.

The Linux kernel upstream has chosen to create and use a separate device tree
for the eMMC variants instead of adding eMMC support existing device tree. These
changes to Linux kernel are queued for Linux 5.4.

https://git.kernel.org/pub/scm/linux/kernel/git/sunxi/linux.git/commit/?h=sunxi/dt-for-5.4&id=02bb66b347ff8115f53948f86b884e008ba385b9

Based on a64-olinuxino_defconfig.

This patch has been tested on A64-OLinuXino-1Ge16GW.
