This change is based on the concept that system user's (overwrite)
settings are held in VPD_RW region, while system owner's (default)
settings are held in VPD_RO region.
Add VPD_RW_THEN_RO region type, so that VPD_RW region is searched
first to get overwrite setting, otherwise VPD_RO region is searched
to get default setting.

CB:34634 expanded the VPD code to also be usable from romstage,
shuffling a few things around and adding some extra infrastructure in
the process. Unfortunately, the changes seem to have only been written
with x86 devices in mind and make coreboot always load the whole VPD
FMAP section (not just the used part) on devices where rdev_mmap() is
not a no-op.
This patch rewrites the VPD code to be based on region_device structures
that only represent the VPD area actually used (rather than the whole
FMAP section), and that only get mapped when accessed. (It would be even
better to pull this concept into the VPD decoder itself, but since that
is taken from third-party code and accesses in early stages aren't very
common, let's not go there for now.) It also moves the copying into
CBMEM to romstage so that late romstage accesses can already benefit
from it, and makes early decoding available in all stages because at
this point, why not.
Also fix a long-standing bug where the 'consumed' counter was not reset
between vpd_decode_string() calls to the RO and the RW VPD.

Convert the remaining files in src/drivers to use SPDX identifiers.
int15.h and default_brightness_levels.asl did not have license headers,
but they were both copied from other GPL2 files, so they should be under
the GPL2 as well.
ne2k.c and drm_dp_helper.h are licensed under custom BSD-like licenses
that do not have an SPDX equivalent, so they are added as exceptions
to the license header lint.

These were often used to distinguish CAR_GLOBAL variables that weren't
directly usable. Since we're getting rid of this special case, also get
rid of the marker.
This change was created using coccinelle and the following script:
@match@
type T;
identifier old =~ "^(g_.*|.*_g)$";
@@
old
@script:python global_marker@
old << match.old;
new;
@@
new = old
if old[0:2] == "g_":
new = new[2:]
if new[-2:] == "_g":
new = new[:-2]
coccinelle.new = new
@@
identifier match.old, global_marker.new;
@@
- old
+ new
@@
type T;
identifier match.old, global_marker.new;
@@
- T old;
+ T new;
@@
type T;
identifier match.old, global_marker.new;
@@
- T old
+ T new
= ...;
There were some manual fixups: Some code still uses the global/local
variable naming scheme, so keep g_* there, and some variable names
weren't completely rewritten.

Summary:
Added a framework to search VPD in romstage before memory is
avilable. vpd_cbmem.c and vpd_premem.c are added for
code specific for premem environment and for environment that
cbmem can be used.
Since global variable is forbidden in romstage. A CAR_GLOBAL
variable is defined in vpd.c. This variable holds VPD binary
blobs' base address and size from memory mapped flash.
The overall flow is:
* The CAR variable g_vpd_blob is initialized if it was not,
either at romstage (before FSP-M execution in case of FSP UPD
customization), or at ramstage.
* At ramstage, during CBMEM_INIT, the VPD binary blob contents
are copied into CBMEM.
* At vpd_find() which may be called at romstage or at ramstage,
it sets storage for a local struct vpd_blob variable.
* The variable gets contents duplicated from g_vpd_blob, if
vpd_find() is called at romstage.
* The variable gets contents obtained from CBMEM, if vpd_find()
is called at ramstage.
Added a call vpd_get_bool(). Given a key/value pair in VPD
binary blob, and name of a bool type variable, set the variable
value if there is a match.
Several checks are in place:
* The key/value length needs to be correct.
* The key name needs to match.
* THe value is either '1' or '0'.
Test Plan:
* Build an OCP MonoLake coreboot image, flash and run.

Update lib_vpd.c (only containing vpd_decode.c) to latest version from
https://chromium.googlesource.com/chromiumos/platform/vpd
The called module (vpd.c) has been also corrected for new lib_vpd
types and constants.
BUG=chromium:967209
TEST=select VPD config on kukui; make; boots on at least kukui boards.

VPD reference: https://chromium.googlesource.com/chromiumos/platform/vpd/+/master/README.md
Copy ChromeOS VPD driver to add support for VPD without CROMEOS.
Possible use case:
* Storing calibration data
* Storing MAC address
* Storing serial
* Storing boot options
+ Now it's possible to define the VPD space by choosing
one of the following enums: VPD_ANY, VPD_RW, VPD_RO.
+ CHROMEOS selects now VPD as part of it.
+ VPD is implemented as driver.
