Merge ACPICA changes, ACPI OS-layer changes, ACPI bus-type and _OSC
support changes and ACPI tables parsing changes for 5.18-rc1:
- Use uintptr_t and offsetof() in the ACPICA code to avoid compiler
warnings regarding NULL pointer arithmetic (Rafael Wysocki).

when passed "acpi=off" in the command line (Rafael Wysocki).

device objects in the Type C code (Rafael Wysocki).

from being used if the platform firmware indicates that it not
supported via _OSC (Rafael Wysocki).

ghes_init() sticks out in acpi_init() because it is the only functions
without an "acpi_" prefix.

From commit e147133a42 ("ACPI / APEI: Make hest.c manage the estatus
memory pool") was merged, ghes_init() relies on acpi_hest_init() to manage
the estatus memory pool. On the other hand, ghes_init() relies on
sdei_init() to detect the SDEI version and (un)register events. The
dependencies are as follows:
ghes_init() => acpi_hest_init() => acpi_bus_init() => acpi_init()
ghes_init() => sdei_init()
HEST is not PCI-specific and initcall ordering is implicit and not
well-defined within a level.
Based on above, remove acpi_hest_init() from acpi_pci_root_init() and
convert ghes_init() and sdei_init() from initcalls to explicit calls in the
following order:
acpi_hest_init()
ghes_init()
sdei_init()

In order to avoid exposing acpi_bus_type to modules, introduce an
acpi_bus_for_each_dev() helper for iterating over all ACPI device
objects and make typec_link_ports() use it instead of the raw
bus_for_each_dev() along with acpi_bus_type.
Having done that, drop the acpi_bus_type export.
No intentional functional impact.

Some x86 ACPI boards have broken AC and battery ACPI devices in their ACPI
tables. This is often tied to these devices using certain PMICs where the
factory OS image seems to be using native charger and fuel-gauge drivers
instead.
So far both the AC and battery drivers have almost identical checks for
these PMICs including both of them having a DMI based mechanism to force
usage of the ACPI AC and battery drivers on some boards even though one
of these PMICs is present, with the same 2 boards listed in both driver's
DMI tables for this.
The only difference is that the AC driver checks for 2 PMICs and the
battery driver only for one. This has grown this way because the other
(Whiskey Cove) PMIC is only used on a few boards (3 known boards) and
although some of these do have non working ACPI battery devices, their
_STA method always returns 0, but that really should not be relied on.
This patch factors out the shared checks into a new
acpi_quirk_skip_acpi_ac_and_battery() helper and moves the AC and
battery drivers over to this new helper.
Note the DMI table is shared with acpi_quirk_skip_i2c_client_enumeration()
and acpi_quirk_skip_serdev_enumeration(), because boards needing DMI quirks
for either of these typically also have broken AC and battery ACPI devices.
The ACPI_QUIRK_SKIP_ACPI_AC_AND_BATTERY quirk is not set yet on boards
already in this DMI table, to avoid introducing any functional changes
in this refactoring patch.
Besided sharing the code between the AC and battery drivers this
refactoring also moves this quirk handling to under #ifdef CONFIG_X86,
removing this x86 specific code from non x86 ACPI builds.

x86 ACPI boards which ship with only Android as their factory image usually
declare a whole bunch of bogus I2C devs in their ACPI tables and sometimes
there are issues with serdev devices on these boards too, e.g. the resource
points to the wrong serdev_controller.
Instantiating I2C / serdev devs for these bogus devs causes various issues,
e.g. GPIO/IRQ resource conflicts because sometimes drivers do bind to them.
The Android x86 kernel fork shipped on these devices has some special code
to remove the bogus I2C clients (and serdevs are ignored completely).
Introduce acpi_quirk_skip_i2c_client_enumeration() and
acpi_quirk_skip_serdev_enumeration() helpers. Which can be used by the I2C/
serdev code to skip instantiating any I2C or serdev devs on broken boards.
These 2 helpers are added to drivers/acpi/x86/utils.c so that the DMI table
can be shared between the I2C and serdev code.
Note these boards typically do actually have I2C and serdev devices, just
different ones then the ones described in their DSDT. The devices which
are actually present are manually instantiated by the
drivers/platform/x86/x86-android-tablets.c kernel module.
The new helpers are only build if CONFIG_X86_ANDROID_TABLETS is enabled,
otherwise they are empty stubs to not unnecessarily grow the kernel size.

Storing CRC-32 hash of the Physical Location of Device
object (_PLD) with devices that have it. The hash is stored
to a new struct acpi_device member "pld_crc".
The hash makes it easier to find devices that share a
location, as there is no need to evaluate the entire object
every time. Knowledge about devices that share a location
can be used in device drivers that need to know the
connections to other components inside a system. USB3 ports
will for example always share their location with a USB2
port.

ACPICA commit 13b9327761955f6e1e5dbf748b3112940c0dc539
The byte length of the Data field in the AEST Processor generic resource
substructure defined in ACPI for the Armv8 RAS Extensions 1.1 is 4Byte.
However, it is defined as a pointer type, and on a 64-bit machine,
it is interpreted as 8 bytes. Therefore, it is changed from a pointer
type unsigned integer 1 byte to an unsigned integer 4 bytes.

ACPICA commit 52abebd410945ec55afb4dd8b7150e8a39b5c960
This macro was only ever used when stuffing pointers into physical
addresses and trying to later reconstruct the pointer, which is
implementation-defined as to whether that can be done. Now that all such
operations are gone, the macro is unused, and should be removed to avoid
such practices being reintroduced.
