Currently ACPI power domain brings devices into D0 state in the "resume
early" phase. Normally this does not cause any issues, as powering up
happens quickly. However there are peripherals that have certain timing
requirements for powering on, for example some models of Elan
touchscreens need 300msec after powering up/releasing reset line before
they can accept commands from the host. Such devices will dominate
the time spent in early resume phase and cause increase in overall
resume time as we wait for early resume to complete before we can
proceed to the normal resume stage.
There are ways for a driver to indicate that it can tolerate device
being in the low power mode and that it knows how to power the device
back up when resuming, bit that requires changes to individual drivers
that may not really care about details of ACPI controlled power
management.
This change attempts to solve this issue at ACPI power domain level, by
postponing powering up device until we get to the normal resume stage,
unless there is early resume handler defined for the device, or device
does not declare any resume handlers, in which case we continue powering
up such devices early. This allows us to shave off several hundred
milliseconds of resume time on affected systems.

A custom DSDT file is mostly used during development or debugging,
and in that case it is quite likely to want to rebuild the kernel
after changing ONLY the content of the DSDT.
This patch adds the custom DSDT as a prerequisite to tables.o
to ensure a rebuild if the DSDT file is updated. Make will merge
the prerequisites from multiple rules for the same target.

clang's Control Flow Integrity requires that every indirect call has a
valid target, which is based on the type of the function pointer. The
*_show() functions in this file are written as if they will be called
from dev_attr_show(); however, they will be called from
sysfs_kf_seq_show() because the files were created by
sysfs_create_group() and the sysfs ops are based on kobj_sysfs_ops
because of kobject_add_and_create(). Because the *_show() functions do
not match the type of the show() member in struct kobj_attribute, there
is a CFI violation.

On HP Pavilion Gaming Laptop 15-cx0xxx, the ECDT EC and DSDT EC share
the same port addresses but different GPEs. And the DSDT GPE is the
right one to use.
The current code duplicates DSDT EC with ECDT EC if the port addresses
are the same, and uses ECDT GPE as a result, which breaks this machine.
Introduce a new quirk for the HP laptop to trust the DSDT GPE,
and avoid duplicating even if the port addresses are the same.

Notice that the table field of struct acpi_table_events_work is never
read and its event field is always equal to ACPI_TABLE_EVENT_LOAD, so
both of them are redundant.
Accordingly, drop struct acpi_table_events_work and use struct
work_struct directly instead of it, simplify acpi_scan_table_handler()
and rename it to acpi_scan_table_notify().
Moreover, make acpi_bus_table_handler() check the event code against
ACPI_TABLE_EVENT_LOAD before calling acpi_scan_table_notify(), so it
is not necessary to do that check in the latter.

If acpi_add_single_object() runs concurrently with respect to
acpi_scan_clear_dep() which deletes a dependencies list entry where
the device being added is the consumer, the device's dep_unmet
counter may not be updated to reflect that change.
Namely, if the dependencies list entry is deleted right after
calling acpi_scan_dep_init() and before calling acpi_device_add(),
acpi_scan_clear_dep() will not find the device object corresponding
to the consumer device ACPI handle and it will not update its
dep_unmet counter to reflect the deletion of the list entry.
Consequently, the dep_unmet counter of the device will never
become zero going forward which may prevent it from being
completely enumerated.
To address this problem, modify acpi_add_single_object() to run
acpi_tie_acpi_dev(), to attach the ACPI device object created by it
to the corresponding ACPI namespace node, under acpi_dep_list_lock
along with acpi_scan_dep_init() whenever the latter is called.

In general, acpi_bus_attach() can only be run safely under

acpi_dep_list_lock, so make acpi_scan_clear_dep() schedule deferred
execution of acpi_bus_attach() under acpi_scan_lock instead of
calling it directly.
This also fixes a possible race between acpi_scan_clear_dep() and
device removal that might cause a device object that went away to
be accessed, because acpi_scan_clear_dep() is changed to acquire
a reference on the consumer device object.

AMD systems from Renoir and Lucienne require that the NVME controller
is put into D3 over a Modern Standby / suspend-to-idle
cycle. This is "typically" accomplished using the `StorageD3Enable`
property in the _DSD, but this property was introduced after many
of these systems launched and most OEM systems don't have it in
their BIOS.
On AMD Renoir without these drives going into D3 over suspend-to-idle
the resume will fail with the NVME controller being reset and a trace
like this in the kernel logs:
```

```
The Microsoft documentation for StorageD3Enable mentioned that Windows has
a hardcoded allowlist for D3 support, which was used for these platforms.
Introduce quirks to hardcode them for Linux as well.
As this property is now "standardized", OEM systems using AMD Cezanne and
newer APU's have adopted this property, and quirks like this should not be
necessary.
