kernel: don't auto-split "firmware" if it has "compatible" DT property
If "compatible" is being used that should trigger a proper parser directly. It's more reliable thanks to not trying parsers one by one. In such case partition shouldn't be split automatically to avoid parsing it twice. Signed-off-by: Rafał Miłecki <rafal@milecki.pl>
