[coreboot] Patch merged into coreboot/master: a9dd41a sconfig: check whether component directory actually exists

the following patch was just integrated into master:
commit a9dd41a1c5f3f00ef790fb071c135900598acab5

sconfig: check whether component directory actually exists

and add drivers/generic/generic back (empty), since it is used by many
    devicetree.cb files.

Without this patch typos in component names in devicetree.cb cause
    the component to be silently ignored.
