of: Add coreboot firmware to excluded default cells list
Google Juniper and other Chromebook platforms have a very old bootloader
which populates /firmware node without proper address/size-cells leading
to warnings:
Missing '#address-cells' in /firmware

These platform won't receive updated bootloader/firmware, so add an
exclusion for platforms with a "coreboot" compatible node. While this is
wider than necessary, that's the easiest fix and it doesn't doesn't
matter if we miss checking other platforms using coreboot.
We may revisit this later and address with a fixup to the DT itself.
