mvebu: add images for additional ESPRESSObin boards

This commit adds support for different iterations of ESPRESSObin.
The added variants are:

ESPRESSObin with soldered eMMC,

ESPRESSObin V7, compared to V5 some passive elements changed and ethernet
ports labels positions have been reversed,

ESPRESSObin V7 with soldered eMMC.

Please refer to:
584d7c5 ("mvebu: new subtarget cortex A53")
for instruction how to boot OpenWrt image placed on SD card. It is
advised for owners of V5 and previous with bootloader based on U-Boot
2015.01, to upgrade the latest version available at:
http://espressobin.net/tech-spec.
