cbfs: Hook up to new CBFS implementation

This patch hooks coreboot up to the new commonlib/bsd CBFS
implementation. This is intended as the "minimum viable patch" that
makes the new implementation useable with the smallest amount of changes
-- that is why some of this may look a bit roundabout (returning the
whole metadata for a file but then just using that to fill out the rdevs
of the existing struct cbfsf). Future changes will migrate the higher
level CBFS APIs one-by-one to use the new implementation directly
(rather than translated into the results of the old one), at which point
this will become more efficient.
