Due to refactoring of Serial IO code in FSP v3163 onwards we need to
set SerialIoUartDebugMode UPD in FSP-M to SkipInit so that SerialIoUart
initialization is skipped in FSP. This makes sure that SerialIo
initialization in coreboot is not changed by FSP.

For unknown reasons FSP skips a whole bunch of SIR (SATA Initialization
Registers) when SataPwrOptEnable=0, which currently is the default in
coreboot and FSP. Even if FSP's default was 1, coreboot would reset it.
This can lead to all sorts of problems and errors, for example:
- links get lost
- only 1.5 or 3 Gbps instead of 6 Gbps
- "unaligned write" errors in Linux
- ...
At least on two boards (supermicro/x11-lga1151-series/x11ssm-f and
purism/librem13v2) SATA is not working correctly and showing such
symptoms.
To let FSP correctly initialize the SATA controller, enable the option
SataPwrOptEnable statically. There is no valid reason to disable it,
which might break SATA, anyway.
Currently, there are no reported issues on CML and CNL, so a change
there could not be tested reliably. SKL/KBL was tested successfully
without any noticable downsides. Thus, only SKL gets changed for now.

Since commit 402fe20e (mb/up/squared: Add mainboard) the UP2's eMMC
maximum host speed was reduced to DDR50, because HS200 showed I/O errors
in the host kernel. We found out that with EDK2 master the correct
Host Speed could not be set properly during EDK2 platform init.
Therefore eMMC would not show up for boot device selection.
This commit sets the eMMC MaxHostSpeed to the designed max value of the
used eMMC on the UP2 board and furthermore drops the override from the
ramstage.c. It's already set in the devicetree.cb.
Though CRC errors are still visible in EDK II debug logs, no other
negative effects have been observed.

In CSE Firmware Custom SKU, CSE region is logically divided into
2 boot partitions. These boot partitions are represented by BP1(RO),
BP2(RW). With CSE Firmware Custom SKU, CSE can boot from either
RO(BP1) or RW(BP2).
The CSE Firmware Custom SKU layout appears as below:
------------- -------------------- ---------------------
|CSE REGION | => | RO | RW | DATA | => | BP1 | BP2 | DATA |
------------- -------------------- ---------------------
In order to support CSE FW update to RW region, below APIs help coreboot
to get info about the boot partitions, and allows coreboot to set CSE
to boot from required boot partition (either RO(BP1) or RW(BP2)).
GET_BOOT_PARTITION_INFO - Provides info on available partitions in the CSE
region. The API provides info on boot partitions like start/end offsets
of a partition within CSE region, and their version and partition status.
SET_BOOT_PARTITION_INFO - Sets CSE's next boot partition to boot from.
With the HECI API, firmware can notify CSE to boot from RO(BP1) or RW(BP2)
on next boot.
As system having CSE Firmware Custom SKU, boots from RO(BP1) after G3,
so coreboot sets CSE to boot from RW(BP2) in normal mode and further,
coreboot ensure CSE to boot from whichever is selected boot partition
if system is in recovery mode.

In order to make it easier to review, this change is being split into
multiple CLs. This is change 1/5 which moves .c files from arch/x86 to
acpi/.
The only acpi files that are still retained under arch/x86 are:
a. acpi_s3.c: This doesn't really deal with ACPI tables. Also, there
are some assumptions in there about SMM which will have to be resolved
if this file needs to be moved to common code.
b. acpi_bert_storage.c/bert_storage.h: This file is currently written
specifically with x86 in mind. So, not moving the file for now.
Motivation for this change: Not all stages on Picasso SoC are targeted
for the same architecture. For example, verstage (if runs before
bootblock) will be targeted for non-x86. This makes it difficult to
add device tree to verstage which would be required to get to SoC
configs from the tree. This is because the device tree on x86
platforms currently contains a lot of devices that require ACPI
related enums and structs (like acpi_gpio, acpi_pld, acpi_dp and so
on). Hence, this change removes all ACPI table support out of
arch/x86.

Hardware tests on the P2B-LS shows the generic hardware power button
is not working anyway - with FADT power button flag set, the board
could not power off with the button.
This change removes the generic hardware power button from all P2B
mainboards and relies completely on the fixed hardware power button.
TEST=Booted on P2B-LS, Linux detects only fixed hardware power
button, button still powers off.

Since the variants' devicetrees are almost identical, convert to

The Librem 15v2 only uses SATA ports 0/1, so the DTLE settings
for ports 2/3 have no consequence. Drop them to make overridetree
conversion cleaner.

Certain boards require SeaBIOS' HARDWARE_IRQ option to be
deselected in order for the platform to boot. Add a Kconfig
to allow selection of HARDWARE_IRQ enablement, and write to
SeaBIOS' .config file in cases where it needs to be disabled.
Deselect the option for google/rambi variants so they boot
with boards defaults.
Test: build/boot google/clapper, verify board boots vs hanging
at boot menu prompt.

Suggested by Nico Huber in CB:38765.
This placement makes the address calculation simpler and
makes its location indepedent of the number of CPUs.
As part of the change in the BIOS resource list address
calculation, the `size` variable was factored out of the
conditional in line 361, thus eliminating the else.
