Add initial support for multiple PCI segment groups. Instead of
modifying secondary in the bus struct introduce a new segment_group
struct element and keep existing common code.
Since all platforms currently only use 1 segment this is not a
functional change. On platforms that support more than 1 segment the
segment has to be set when creating the PCI domain.

The physical address size of the System-on-Chip (SoC) can be different
from the CPU physical address size. These two different physical
address sizes should be used for settings of their respective field.
For instance, the physical address size related to the CPU should be
used for MTRR programming while the physical address size of the SoC
should be used for MMIO resource allocation.
Typically, on Meteor Lake, the CPUs physical address size is 46 if TME
is disabled and 42 if TME is enabled but Meteor Lake SoC physical
address size is always 42. As a result, MTRRs should reflect the TME
status while coreboot MMIO resource allocator should always use
42 bits.
This commit introduces `SOC_PHYSICAL_ADDRESS_WIDTH' Kconfig to set the
physical address size of the SoC for those SoCs.

- The 'acpi_get_pptt_topology' hook is mandatory once ACPI_PPTT

which describes the relationship between CPUs and caches. The hook
can be provided by, for example, mainboard code.

Previously acpigen_pop_len always wrote a 3 byte PkgLength to the 3
bytes reserved by acpigen_write_len_f. After this patch acpigen_pop_len
encodes PkgLength in 1-3 bytes depending on the PkgLength. When less
than the 3 bytes that were previously reserved in the corresponding
acpigen_write_len_f call are needed for PkgLength, the payload data will
be moved back by the number of reserved bytes that aren't needed for the
PkgLength.
This fixes the problem that the Windows AML parser doesn't like a 3 byte
PkgLength being used for the size of the buffer containing UTF-16
strings when the length could be encoded in a single PkgLength byte. In
that case, Windows previously ignored the whole SSDT containing this
larger than necessary PkgLength encoding. It should however be noted
that the ACPI 6.4 spec doesn't specify if it's required to always use
the most compact possible encoding of the PkgLength or not. Since iasl
generates the shortest possible PkgLength encoding, it's also a good
idea to make coreboot's acpigen do the same although it's not required
by the specification.
With this patch applied, Windows still boots on Mandolin and the time it
takes to write the tables doesn't change. To measure the times, the log
level in bs_sample_time was increased to BIOS_CRIT and the console log
level was increased to BIOS_CRIT too to only get those times as output.

Since d8f2dce "acpi.c: Swap XSDT and RSDT for adding/finding tables"
XSDT is primarily used to add new tables or to find the S3 resume vector.
However with QEMU coreboot does not generate most ACPI tables but takes
them from whatever QEMU provides. Qemu only creates an RSDT and lacks an
XSDT.
To keep the codebase simple with the assumption that XSDT is always
present, create an XSDT based on the existing RSDT and update the
address in RSDP.

In soundwire.h, SOUNDWIRE_DPN MIN & MAX are set to 1 and 14. When
creating the dpn array, the length was set to MAX - MIN or 13, numbered
0 to 12.
When accessing the array, the code was bailing out if a value greater
than MAX was trying to be accessed, so the array was able to be overrun
by two structure lengths.
Fix this problem by:
1) Not subtracting the MIN value when creating the array, which does
waste a little space. If anyone wants to refactor the code to fix that,
please feel free.
2) Breaking out of the loop when the port is equal to the MAX port
number instead of just when it's greater than the max port number.

If ACPI is above 4G it's not possible to have a valid RSDT pointer in

On other architectures RSDT is often skipped, e.g. aarch64. On top of
that the OS looks at XSDT first. So unconditionally using XSDT and not
RSDT is fine.
This also deal with the ACPI pointer being above 4G. This currently
never happens with x86 platforms.

From the Linux documentation (Documentation/PCI/acpi-info.rst):
[6] PCI Firmware 3.2, sec 4.1.2:
If the operating system does not natively comprehend reserving the
MMCFG region, the MMCFG region must be reserved by firmware. The
address range reported in the MCFG table or by _CBA method (see Section
4.1.3) must be reserved by declaring a motherboard resource. For most
systems, the motherboard resource would appear at the root of the ACPI
namespace (under \_SB) in a node with a _HID of EISAID (PNP0C02), and
the resources in this case should not be claimed in the root PCI bus’s
_CRS. The resources can optionally be returned in Int15 E820 or
EFIGetMemoryMap as reserved memory but must always be reported through
ACPI as a motherboard resource.
So in order for the OS to use ECAM MMCONF over legacy PCI IO
configuration, a PNP0C02 HID device needs to reserve this region.
As no AMD platform has this defined in DSDT this fixes Linux using
legacy PCI IO configuration over MMCONF. Tianocore messes with e820
table in such a way that it prevents Linux from using PCIe ECAM. This
change fixes that problem.
