add checks for depthcharge and coreboot

Vendors start making contributions to Depthcharge, so the
Signed-off-by: clause will be useful.

Coreboot patches were not being checked at all until this change, it
has been decided to follow the kernel style for now, ignoring certain
violations, more exceptions could be added later as required.

TEST=attempts to upload coreboot patch with lines longer than 80
    columns fail now.
