Denverton is a special version of IFD2 flash layout. It defines
10GbE firmware regions (11/12) and the IE (10) region which
other IFD2 platforms do not have. Denverton does not include the
legacy GbE region (3) or the EC region (8) which other IFD2

`PLATFORM_IFD2` macro is more generic tag that can be associated with
early next SoC platform development which using IFDv2.
The current assumption is that newer SoC platform still uses the same
SPI/eSPI frequency definition being used for latest platform(TGL, ADL)
and if the frequency definition is updated later, `PLATFORM_IFD2' will
use latest frequency definition for early next SoC development.
And once upstream is allowed for new platform, platform name will be
added in tool later.

Commit f1e401c6cb (util/cbfstool/flashmap/fmap.c: fix fmaptool
endianness bugs on BE) makes use of endianness conversion macros
in cbfstool's FMAP code, which is also used by ifdtool. At least
on Linux, the <endian.h> header provides these helpers, but only
when `__USE_MISC` is defined, which is defined in the <ctypes.h>
header when `_DEFAULT_SOURCE` is defined. This was accounted for
in `Makefile.inc`, but not in `Makefile`. As a result, trying to
build ifdtool as a standalone tool (i.e. not as part of building
a coreboot image) results in build errors because the endianness
conversion macros are not defined.
Define `_DEFAULT_SOURCE` in `Makefile` to fix the build errors.

ifdtool uses `chipset` information to determine how certain straps
are decoded. This has been used for IFDv1 platforms as well as IFDv2
platforms (CHIPSET_500_600_SERIES_TIGER_ALDER_POINT).
IFDv2 platforms are all expected to pass in `-p` argument to identify
the platform. This platform information can be used to identify the
appropriate chipset information. For IFDv1 since `-p` argument is not
provided, ifdtool needs to use certain fields in the descriptor
(e.g. strap length) for unique identification of IFDv1 chipset.
This change updates `check_ifd_version()` function to:
1. Determine if IFD version is v1 or v2 based on `-p` argument.
If `-p` is not provided, it assumes that the platform is using IFDv1.
2. Based on IFD version, it calls either `ifd2_platform_to_chipset()`
or `ifd1_guess_chipset()` to determine chipset information.
This fixes the issue reported with CB:44815, where ifdtool is unable
to identify Alder Lake chipsets.

This patch creates a new commonlib/bsd subdirectory with a similar
purpose to the existing commonlib, with the difference that all files
under this subdirectory shall be licensed under the BSD-3-Clause license
(or compatible permissive license). The goal is to allow more code to be
shared with libpayload in the future.
Initially, I'm going to move a few files there that have already been
BSD-licensed in the existing commonlib. I am also exracting most
contents of the often-needed <commonlib/helpers.h> as long as they have
either been written by me (and are hereby relicensed) or have an
existing equivalent in BSD-licensed libpayload code. I am also
relicensing <commonlib/compression.h> (written by me) and
<commonlib/compiler.h> (same stuff exists in libpayload).
Finally, I am extracting the cb_err error code definitions from
<types.h> into a new BSD-licensed header so that future commonlib/bsd
code can build upon a common set of error values. I am making the
assumption here that the enum constants and the half-sentence fragments
of documentation next to them by themselves do not meet the threshold of
copyrightability.
