ACPI: x86: Move acpi_quirk_skip_serdev_enumeration() out of CONFIG_X86_ANDROID_TABLETS

[ Upstream commit 7c86e17455de1a442ec906d3449148b5e9a218a4 ]

Some recent(ish) Dell AIO devices have a backlight controller board
connected to an UART.

This UART has a DELL0501 HID with CID set to PNP0501 so that the UART is
still handled by 8250_pnp.c. Unfortunately there is no separate ACPI device
with an UartSerialBusV2() resource to model the backlight-controller.

The next patch in this series will use acpi_quirk_skip_serdev_enumeration()
to still create a serdev for this for a backlight driver to bind to
instead of creating a /dev/ttyS0.

This new acpi_quirk_skip_serdev_enumeration() use is not limited to Android
X86 tablets, so move it out of the ifdef CONFIG_X86_ANDROID_TABLETS block.

Merge ACPI thermal driver changes for 6.6-rc1.

This reworks the ACPI thermal driver to use a table of generic trip
point structures on top of the internal representation of trip points
and removes thermal zone callbacks that are not necessary any more
from it.

It requires some relatively small changes to be made in the thermal core
too and it is based on top of changes reworking ACPI device notification
handling that are included in this merge.

ACPI: TAD: Install SystemCMOS address space handler for ACPI000E

Currently, the SystemCMOS address space handler is installed for the
ACPI RTC devices (PNP0B00/PNP0B01/PNP0B02) only. But there are platforms
with SystemCMOS Operetion Region defined under the ACPI Time and Alarm
Device (ACPI000E), which is used by the ACPI pre-defined control methods
like _GRT (Get the Real time) and _SRT (Set the Real time).

When accessing these control methods via the acpi_tad sysfs interface,
missing SystemCMOS address space handler causes errors like below
[ 478.255453] ACPI Error: No handler for Region [RTCM] (00000000a8d2dd39) [SystemCMOS] (20230331/evregion-130)

[ 478.255464] No Arguments are initialized for method [_GRT]
[ 478.255465] ACPI Error: Aborting method \_SB.AWAC._GRT due to previous error (AE_NOT_EXIST) (20230331/psparse-529)

Export two APIs for SystemCMOS address space handler from acpi_cmos_rtc
scan handler and install the handler for the ACPI Time and Alarm Device
from the ACPI TAD driver.

ACPI: bus: Introduce wrappers for ACPICA notify handler install/remove

Introduce new functions acpi_dev_install_notify_handler() and
acpi_dev_remove_notify_handler(), to install and remove, respectively,
a handler for AML Notify() operations targeted at a given ACPI device
object. They will allow drivers to install Notify() handlers directly
instead of providing an ACPI driver .notify() callback to be invoked
in the context of a Notify() handler installed by the ACPI bus type
code. In particular, this will help platform drivers to provide
Notify() handlers for the ACPI companions of the platform devices
they bind to.

These functions are replacements for acpi_device_install_notify_handler()
and acpi_device_remove_notify_handler(), respectively, and after all
drivers switch over to using them, the old ones will be dropped.
