board: amlogic: vim3: fix setup ethernet mac from efuse
Fix reading built-in ethernet MAC address from efuse
NOTE: MAC is stored in ASCII format, 1bytes = 2characters by 0 offset
if mac from efuse not valid we use meson_generate_serial_ethaddr
NOTE: remake odroid-n2.c from Neil Armstrong <narmstrong@baylibre.com>
