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.

Until now, the buildOpts.c files were primarily made out of copy-pasted
AGESA options, commented-out definitions and several useless comments;
that is, the materialization of technical debt in GCC-parsable form...
Until now.
It is assumed that the boards in the tree still boot. So, by comparing
their settings, we can extract saner defaults to place into AGESA. Many
of the settings were common across all boards of the same family, so we
promote those values to default settings. In some cases flipping a flag
was required, so the macros to alter that option had to be adapted as
well. Since those AGESA versions are expected to never receive updates,
it should not be a problem to change their files to suit our needs.
As a result, all but two buildOpts.c files now have less than 100 lines.
AGESA f14 boards need less than 50 lines, and f15tn/f16kb just require
about 60 or 70 lines in those files. Hopefully, this will make porting
more mainboards using AGESA f14/f15tn/f16kb a substantially easier task.
TEST=Use abuild --timeless to check that all AGESA f14/f15tn/f16kb
mainboards result in identical coreboot binaries.

Matching the same behavior change in depthcharge's FIT image code
(CL:2212466), this patch changes the order in which compat strings
involving revision and SKU numbers are matched when looking for a
compatible device tree. The most precise match (board-revX-skuY) is
still the highest priority, but after that we will now first check for
revision only (board-revX) and then for SKU only (board-skuY). The
reason for this is that SKU differentiation is often added later to a
project, so device trees for earlier revisions may not have SKU numbers
defined. So if we have a rev0 board (with sku0 as the "default SKU",
because the board only started having different SKUs with rev1) we want
it to match the board-rev0 device tree, not board-sku0 which was added
as an alias to board-rev1-sku0 to provide the best known default for
potential later revisions of that SKU.
