As a part of trying to get our boot time as low as possible, any delays
in the code should try to be refactored out. This removes the 50ms
delay in the WIFI sequence by enabling power and putting the wifi module
into reset in bootblock, then bringing it out of reset in ramstage.
This is significantly longer than the 50ms requirement. The reset GPIO
was already being set high in ramstage, so that code didn't need to be
added.

Currently, the PCIe bridge 00:15.2 is not detected by coreboot, causing
the connected network device also to be missing.
This is caused by not configuring the third of the four PCIe General
Purpose Ports (GPP) of the AMD Fusion Controller Hub (FCH), which can be
exposed as one to four PCIe devices.
So, enable it in AGESA but disable enumeration in coreboot. Otherwise,
the serial console stops working in romstage after
[…]

PCI: 00:15.1 cmd <- 06

The idea is to split the “mainboard” category into “variants” and
“carrierboards”, in the case when we use the COMe module together
with the Carrier Board instead of a single monolithic motherboard.
Previously, the “variants” category defined the type of motherboard,
which has a number of differences from the base one, for example, it
differed in the size or type of memory, and in the configuration of
the interfaces. Thus, there is no need to create a separate directory
in src/mainboard for a board that is similar in configuration to the
base board. But for a COMe module, “variants” contains different
variants of only this module, and the entire Carrier Board configuration
is allocated to a separate category - “carrierboards”, and each of the
variants can be used with one of the many boards in “carrierboards”.
For example, in the case of the Kontron mAL10 COMe module, variant
refers to the COMe-mAL10 or COMe-m4AL10 module type. They differ in the
type of memory (DDR3L or DDR4), and maybe they differ in some chips (see
more in https://www.kontron.com/products). However, all variants contain
the same type of processor/SoC.
The "carrierboards" directory can be able contain both the Kontron's
Evalution carrier boards (such as Eval Carrier2 T10 and COMe
Ref.Carrier-i T10 TNI) and third party vendor backplanes that are
compatible with the COMe modules from “variants”.
Thus, the src/mainboard/<module-name> directory contains the common
configuration code for all variants from src/mainboard/<module-name>/
variants, which can be supplemented/redefined with a configuration from
src/mainboard/<module-name>/carrierboard/<vendor-carrierboard-name>.
This architectural solution will be able to systematize and simplify
understanding of the code structure for COMe modules and will allow
vendors to add/maintain their code in a separate directory.
This work is also the first step towards to union of all carrierboards
into the global category in src/carrierboard on a par with all boards
from src/mainboard.
The patch takes this into account in the build system and adds
CARRIER_DIR component to use the “carrierboards” category, as it has
done for VARIANT_DIR.
TEST = Build ROM image for Kontron mAL10 COMe module together with T10
TNI carrier board (https://review.coreboot.org/c/coreboot/+/39133).
