There is no existing documentation on how `device ref` and aliases work
in the devicetree, and the behavior around devices not being in the same

When running multiple tests, e.g. by using unit-tests target, it is hard
to differentiate, which output comes from which file and/or
configuration. This patch makes the output easier to analyze and
understand by using new wrapper macro cb_run_group_tests(). This macro
uses __TEST_NAME__ value (containing test path and Makefile test name)
as a group name when calling cmocka group runner.
Example:
Test path: tests/lib/
Makefile test name: cbmem_stage_cache-test
Test group array name: tests
Result: tests/lib/cbmem_stage_cache-test(tests)

default by changing its enum value to 0 and remove its configuration
from all related devicetrees.
If `common_soc_config.chipset_lockdown` is not configured with
something else in the devicetree, then `CHIPSET_LOCKDOWN_COREBOOT`
is used.

This was originally several commits that had to be squashed into one
because the intermediate states weren't able to build coreboot:
- one to remove everything that wasn't our own code, leaving only
regex.[ch], toada.c, description.md and Makefile.inc.
- one to copy in Linux 5.13's scripts/kconfig and adapt Makefile.inc
to make the original Makefile work again.
- adapt abuild to use olddefconfig, simplifying matters.
- apply patches in util/kconfig/patches.
- Some more adaptations to the libpayload build system.
The patches are now in util/kconfig/patches/, reverse applying them
should lead to a util/kconfig/ tree that contains exactly the Linux
version + our own 5 files.

Using the linker's --wrap feature has the downside that it only covers
references across object files: If foo.c defines a() and b(), with b
calling a, --wrap=a does nothing to that call.
Instead, use objcopy to mark a weak and global so it can be overridden
by another implementation, but only for files originating in src/.
That way mocks - implemented in tests/ - become the source of truth.
TEST=Had such an issue with get_log_level() in a follow-up commit, and
the mock now takes over. Also, all existing unit tests still pass.

Soft straps, that can be configured by the vendor in the Intel Flash
Image Tool (FIT), can influence some pads' default state. It is possible
to select either a native function or GPIO mode for some pads on
non-server SoCs, while on server SoCs most pads can be controlled.
Thus, add a recommendation to always configure all pads for a board to
guarantee integrity between different board or vendor firmware revisions
where the soft straps might have been changed.

Intel PDGs starting from Skylake / Sunrise Point state that, different
from the general recommendation in digital electronics, unconnected
GPIOs defaulting to GPIO mode do explicitly not require termination.
The reason for this is, that these GPIOs have the `GPIORXDIS` bit set,
which effectively disconnects the pad from the internal logic by
disabling the input buffer.
This bit - besides `GPIOTXDIS` - can also be set explicitly by using
the gpio macro `PAD_NC(pad, NONE)`.
In some cases, a pull resistor may be required due to bad board design
or when a vendor sets the RX/TX disable bits together with a pull
resistor and schematics are not available to check if the pad is really
unconnected or just unused. In this case the pull resistor should be
kept.
Pads defaulting to native functions usually don't need special handling.
However, when pads requiring external pull-ups are missing these due to
bad board design, they should be configured with `PAD_NC` to disconnect
them internally.
Rewrite the documentation to reflect these new findings.
Also clarify the comment in soc/intel gpio code accordingly.
