[flashrom] [PATCH] Kill spurious cbtable related board enable warning

[Carl-Daniel Hailfinger]

Boards with coreboot have a cbtable containing vendor and board name.
flashrom tries to match these with board enable entries in its database.
If no such board enable entry exists because the board doesn't need one,
flashrom complains. Silence that complaint.
