A new header fch.h was created to store registers used by different AMD
drivers.  This header was included by i2c-piix4 in
commit 624b0d5696a8 ("i2c: piix4, x86/platform: Move the SB800 PIIX4 FCH
definitions to <asm/amd/fch.h>"). To prevent compile failures on non-x86
archs i2c-piix4 was set to only compile on x86 by commit 7e173eb82ae9717
("i2c: piix4: Make CONFIG_I2C_PIIX4 dependent on CONFIG_X86").
This was not a good decision because loongarch and mips both actually
support i2c-piix4 and set it enabled in the defconfig.

Move the header to a location accessible by all architectures.

Fixes: 624b0d5696a89 ("i2c: piix4, x86/platform: Move the SB800 PIIX4 FCH definitions to <asm/amd/fch.h>")

sensor_config is not used anywhere and its struct int3472_sensor_config

At the moment the atomisp has duplicate code for parsing Intel camera
sensor GPIOS and calling the special 79234640-9e10-4fea-a5c1-b5aa8b19756f
_DSM to get the GPIO type and map it to the sensor.

Export int3472_discrete_parse_crs() so that the atomisp driver can reuse
the INT3472 code for this.

The intent is to re-use the INT3472 code for parsing Intel camera sensor
GPIOs and mapping them to the sensor for the atomisp driver, which
currently has duplicate code.

On atomisp devices there is no special INT3472 ACPI device, instead
the Intel _DSM to get the GPIO type is part of the ACPI device for
the sensor itself.

To deal with this the mapping is done from ipu_bridge_init() instead of
from a platform-device probe() function, there is no device to tie
the lifetime of the gpiod_get() calls done by the INT3472 code to.

Switch from devm_gpiod_get() to plain gpiod_get() + explicit gpiod_put()
calls, to prepare for the code being re-used in the atomisp driver.

Move the common.h header file to include/linux/platform_data/x86/int3472.h
and add a "INTEL_INT3472" kernel-symbol-namespace to the exported symbols.

This is a preparation patch for exporting some more symbols for re-use in
the atomisp driver.

Adjust how the CSEE direct call hack is used.

The results of months of testing combined with help from ASUS to
determine the actual cause of suspend issues has resulted in this
refactoring which immensely improves the reliability for devices which
do not have the following minimum MCU FW version:
- ROG Ally X: 313
- ROG Ally 1: 319

For MCU FW versions that match the minimum or above the CSEE hack is
disabled and mcu_powersave set to on by default as there are no
negatives beyond a slightly slower device reinitialization due to the
MCU being powered off.

As this is set only at module load time, it is still possible for
mcu_powersave sysfs attributes to change it at runtime if so desired.

Introduce a configuration option that allows users to build the
intel_pmc_ipc driver without ACPI support. This is useful for
systems where ACPI is not available or desired.

Based on the discussion from the patch [1], it was necessary to
provide this option to accommodate specific use cases.

- Exports intel_pmc_ipc() for host access to the PMC IPC mailbox
- Enables the host to access specific SoC registers through the PMC
firmware using IPC commands. This access method is necessary for
registers that are not available through direct Memory-Mapped I/O (MMIO),
which is used for other accessible parts of the PMC.
