kconfig: automatically include mainboards

This change switches all mainboard vendors and mainboards
to be autoincluded by Kconfig, rather than having to be mentioned
explicitly.

This means, vendor and mainboard directories are becoming more
"drop in", e.g. be placed in the coreboot directory hierarchy
without having to modify any higher level coreboot files.

The long term plan is to enable out of tree mainboards / components
to be built with a given coreboot version (given that the API did
not change)
