The Linux ChromeOS EC driver now looks for 3 new properties under each

switches for USB 2/3 muxing, SBU lines, and CC lines. It uses the new
function, soc_get_pmc_mux_device() to retrieve the device.

The ChromeOS EC is adding new entries to its USBC.CONx devices (see later
patch), and it needs to get access to the PMC.MUX device so that its
ACPI path can be retrieved. This provides a weak function to return NULL
for all Intel SoCs except for Tiger Lake, which locates the device if it
is found in the devicetree.

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.

This change adds back CB:39487 which was reverted as part of
CB:41412. Now that the resource allocator is split into old(v3) and
new(v4), this change adds support for allocating resources above 4G
boundary with the new allocator v4.
Original commit message:
This change adds support for allocating resources above the 4G
boundary by making use of memranges for resource windows enabled in
the previous CL.
It adds a new resource flag IORESOURCE_ABOVE_4G which is used in the
following ways:
a) Downstream device resources can set this flag to indicate that they
would like to have their resource allocation above the 4G
boundary. These semantics will have to be enabled in the drivers
managing the devices. It can also be extended to be enabled via
devicetree. This flag is automatically propagated by the resource
allocator from downstream devices to the upstream bridges in pass
1. It is done to ensure that the resource allocator has a global view
of downstream requirements during pass 2 at domain level.
b) Bridges have a single resource window for each of mem and prefmem
resource types. Thus, if any downstream resource of the bridge
requests allocation above 4G boundary, all the other downstream
resources of the same type under the bridge will be allocated above 4G
boundary.
c) During pass 2, resource allocator at domain level splits
IORESOURCE_MEM into two different memory ranges -- one for the window
below 4G and other above 4G. Resource allocation happens separately
for each of these windows.
d) At the bridge level, there is no extra logic required since the
resource will live entirely above or below the 4G boundary. Hence, all
downstream devices of any bridge will fall within the window allocated
to the bridge resource. To handle this case separately from that of
domain, initializing of memranges for a bridge is done differently
than the domain.
Limitation:
Resources of a given type at the bridge or downstream devices
cannot live both above and below 4G boundary. Thus, if a bridge has
some downstream resources requesting allocation for a given type above
4G boundary and other resources of the same type requesting allocation
below 4G boundary, then all these resources of the same type get
allocated above 4G boundary.

* Correctly advertise ECC support, max DIMM count and max capacity
* CAPID0_A hasn't changed since SNB, but most EDS mark the bits as

* Assume the same bits for Tiger Lake as for Ice Lake
* Assume the same bits for Skylake as for Coffee Lake
* Add CAPID0_A to Icelake headers
