This can serve, for instance, as a basis to add new SoCs to
coreboot. Starting with a buildable commit should help with
the review of the actual code, and also avoid any regressions
when common coreboot code changes.
As the example code itself is build-tested, it should advance
with coreboot and can't rot like documentation might. It also
serves as a check what APIs need to be implemented with the
default Kconfig settings.

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.

1. Be BSD-licensed so it can evetually be shared with libpayload.
2. Allow generating/verifying a metadata hash for future CBFS per-file
verification (see [1][2]).
3. Be very careful about reading (not mmaping) all data only once, to be
suitable for eventual TOCTOU-safe verification.
4. Make it possible to efficiently implement all current and future
firmware use cases (both with and without verification).
The main primitive is the cbfs_walk() function which will traverse a
CBFS and call a callback for every file. cbfs_lookup() uses this to
implement the most common use case of finding a file so that it can be
read. A host application using this code (e.g. coreboot, libpayload,
cbfstool) will need to provide a <cbfs_glue.h> header to provide the
glue to access the respective CBFS storage backend implementation.
This patch merely adds the code, the next patch will integrate it into
coreboot.

(Note: In early discussions the metadata hash was called "master hash".)

There's no need for the global list of files to ignore, so use git's
ability to work with more local configuration.

It is only used in a single file, on two functions that already check
whether coreboot is running on a Haswell or a Broadwell processor.

Flesh out the PCH configuration into a separate chip. Keep it within the
Broadwell SoC directory for now, to ease moving files around. The boards
were prepared beforehand and the devicetrees require next to no changes.
Tested on out-of-tree Acer Aspire E5-573, still boots.
