A fairly common thing in ACPI is notifying a device when some kind of
device-specific event happens; this function simplifies writing this
pattern.

DPTF has several options on how to control the fan (fine-grained speed
control, minimum speed change in percentage points, and whether or not
the DPTF device should notify the Fan if it detects low speed).
Individual TSRs can also set GTSH, which is the amount of hysteresis
inherent in the measurement, either from circuitry (if analog), or in
firmware (if digital).

This change adds support for emitting the PPCC table, which describes
the ranges available as knobs for DPTF to tune. It can support min/max
power, min/max time window for averaging, and the minimum adjustment size
(granularity or step size) of each power limit. The current implementation
only supports PL1 and PL2.

This change adds support for generating the _FPS table for the DPTF Fan

applied to the system in order to actively cool it. The information
includes fan speed at a (rough) percentage level, fan speed in RPM,
potential noise level in centibels, and power in mA.

As per ACPI spec, GpioIo does not have any polarity associated with
it. Linux kernel uses `active_low` argument within GPIO _DSD property
to allow BIOS to indicate if the corresponding GPIO should be treated
as active low. Thus, if GPIO has active high polarity or if it does
not have any polarity associated with it, then the `active_low`
argument is supposed to be set to 0.
Having a `polarity` field in acpi_gpio seems confusing because GPIOs
might not always have polarity associated with them. Example, in case
of DMIC-select GPIO where 0 means select DMIC0 and 1 means select
DMIC1, there is no polarity associated with the GPIO. Thus, it would
be clearer for mainboard to use macros without having to specify a
particular polarity. In order to enable mainboards to provide GPIO
information without polarity for GpioIo usage, this change also adds
`ACPI_GPIO_OUTPUT` and `ACPI_GPIO_INPUT` macros.

Advertising SMI triggers in FADT is only valid if we exit with
SMI installed. There has been some experiments to delay SMM
installation to OS, yet there are new platforms that allow some
configuration access only to be done inside SMM.
Splitting static HAVE_SMI_HANDLER variable helps to manage cases
where SMM might be both installed and cleared prior to entering
payload.

There have been changes to the way device properties are supported
in Linux[1] and Windows[2] which add flexibilty:
- non-standard UUIDs can be used instead of only ACPI_DP_UUID
- support for multiple different packages within the _DSD that
associate different properties with unique UUIDs.
To handle this I extracted the part that does the write of UUID and
properties to a separate function and defined a new PACKAGE type
which has the custom UUID as a name and can be used the same way that
child properties are today.
For example a PCIe root port for a USB4 port has a standard property
indicating the USB4 reference, and then two custom properties which
are defined for different attributes.
Example code:
/* Create property table */
acpi_dp *dsd = acpi_dp_new_table("_DSD");
acpi_dp_add_reference(dsd, "usb4-port", usb4_path);
/* Add package for hotplug */
acpi_dp *pkg = acpi_dp_new_table("6211e2c0-58a3-4af3-90e1-927a4e0c55a4");
acpi_dp_add_integer(pkg, "HotPlugSupportInD3", 1);
acpi_dp_add_package(dsd, pkg);
/* Add package for external port info */
pkg = acpi_dp_new_table("efcc06cc-73ac-4bc3-bff0-76143807c389");
acpi_dp_add_integer(pkg, "ExternalFacingPort", 1);
acpi_dp_add_package(dsd, pkg);
/* Write all properties */
acpi_dp_write(dsd);
Resulting ACPI:
Scope (\_SB.PCI0.TRP0)
{
Name (_DSD, Package ()
{
ToUUID ("daffd814-6eba-4d8c-8a91-bc9bbf4aa301")
Package ()
{
Package () { "usb4-port", \_SB.PCI0.TDM0.RHUB.PRTA }
},
ToUUID ("6211e2c0-58a3-4af3-90e1-927a4e0c55a4"),
Package ()
{
Package () { "HotPlugSupportInD3", One }
},

This change uses the previously added SoundWire definitions to provide
functions that generate ACPI Device Properties for SoundWire
controllers and codecs.
A SoundWire controller driver should populate
`struct soundwire_controller` and pass it to
soundwire_gen_controller(). This will add all of the defined master
links provided by the controller.
A SoundWire codec driver should populate the necessary members in
struct soundwire_codec and pass it to soundwire_gen_codec().
Several properties are optional and depend on whether the codec itself
supports certain features and behaviors.
The goal of this interface is to handle all of the properties defined
in the SoundWire Discovery and Configuration Specification Version
1.0 so that controller and codec drivers do not need to all have code
for writing standard properties.
Both of these functions also provide a callback method for adding
custom properties that are not defined by the SoundWire DisCo
Specification. These properties may be required by OS drivers but are
outside of the scope of the SoundWire specification itself.
This code is tested with controller, codec, and mainboard
implementations in subsequent commits.
