mvebu: increase compat version for SolidRun ClearFog Base

When changing the Pro variant to DSA, the ethernet interface rename
script was dropped by all devices to keep them in sync:

  be309bfd7445 ("mvebu: drop 06_set_iface_mac preinit script")

Therefore, network config will be broken after upgrade for the
Base variant as well. Increase the compat version and provide a
message to signal that to the users.
