[DEB] Add A12 Ethernet and 8 GB RAM overlays

and fw_printenv/fw_setenv configs with a default U-Boot environment. This fixes boot issues with latest StarFive U-Boot builds, which strictly boot from a partition 3 with FAT filesystem only. Our environment uses a generic approach to boot from any filesystem of any partition of any boot media, based on a "boot_targets" variable. Also move packaging files out of workflow file into pre-created dir structure. Signed-off-by: MichaIng <[email protected]>
