Add support for an MCU powersave WMI call. This is intended to set the
MCU in to a low-power mode when sleeping. This mode can cut sleep power
use by around half.

The previous work to allow the MCU to be resumed correctly after sleep
and resume tried to take the shortest possible time. However as work
continues in various other parts of the s2idle subsystems it has shown
that it wasn't entirely reliable.
If the MCU disable/enable call is done correctly the MCU fully removes
its USB endpoints, and this shows as a full USB device reconnection on
resume. When we tried to short this as much as possible sometimes the
MCU doesn't get to complete what it needs to do before going to low-power
and this affected the reconnection.
Through trial it is found that the minimum time required is approx 1200ms
to allow a proper disconnect and disable, and the same amount of time on
resume is required to prevent a rapid disconnect/reconnect happening on
seemingly random occasions. To be safe the time is now 1500ms for msleep.

Laptops with any of the ppt or nv tunables default to the minimum setting
on boot so we can safely assume a stored value is correct.
This patch adds storing of those values in the local struct, and enables
reading of those values back. To prevent creating a series of byte holes
in the struct the "<name>_available" bool is removed and
`asus_sysfs_is_visible()` uses the `ASUS_WMI_DEVID_<name>` directly.

Multiple WMI events can be received concurrently, so multiple instances
of xiaomi_wmi_notify() can be active at the same time. Since the input

ACER Vivobook Flip (TP401NAS) virtual intel switch is implemented as
follow:
Device (VGBI)
{
Name (_HID, EisaId ("INT33D6") ...
Name (VBDS, Zero)
Method (_STA, 0, Serialized) // _STA: Status ...
Method (VBDL, 0, Serialized)
{
PB1E |= 0x20
VBDS |= 0x40
}
Method (VGBS, 0, Serialized)
{
Return (VBDS) /* \_SB_.PCI0.SBRG.EC0_.VGBI.VBDS */
}
...
}
By default VBDS is set to 0. At boot it is set to clamshell (bit 6 set)
only after method VBDL is executed.
Since VBDL is now evaluated in the probe routine later, after the device
is registered, the retrieved value of VBDS was still 0 ("tablet mode")
when setting up the virtual switch.
Make sure to evaluate VGBS after VBDL, to ensure the
convertible boots in clamshell mode, the expected default.

devm_device_add_groups() is being removed from the kernel, so move the
hsmp driver to use device_add_groups() instead. The logic is identical,
when the device is removed the driver core will properly clean up and
remove the groups, and the memory used by the attribute groups will be
freed because it was created with dev_* calls, so this is functionally
identical overall.

The Z830 has some buttons that will only work properly as "quickstart"
buttons. To enable them in that mode, a value between 1 and 7 must be
used for HCI_HOTKEY_EVENT. Windows uses 0x5 on this laptop so use that for
maximum predictability and compatibility.
As there is not yet a known way of auto detection, this patch uses a DMI
quirk table. A module parameter is exposed to allow setting this on other
models for testing.

Since the meaning of those events is not standardized, userspace

show() should only use sysfs_emit() or sysfs_emit_at() when formatting
the value to be returned to user space.

This changes all *_show attributes in asus-wmi.c to use sysfs_emit()
instead of the older method of writing to the output buffer manually.

Pull sound updates from Takashi Iwai:
"This was a relatively calm development cycle. Most of changes are
rather small device-specific fixes and enhancements. The only
significant changes in ALSA core are code refactoring with the recent
cleanup infrastructure, which should bring no functionality changes.
Some highlights below:
Core:
- Lots of cleanups in ALSA core code with automatic kfree cleanup and
locking guard macros
- New ALSA core kunit test
ASoC:
- SoundWire support for AMD ACP 6.3 systems
- Support for reporting version information for AVS firmware
- Support DSPless mode for Intel Soundwire systems
- Support for configuring CS35L56 amplifiers using EFI calibration
data
- Log which component is being operated on as part of power
management trace events.
- Support for Microchip SAM9x7, NXP i.MX95 and Qualcomm WCD939x
HD- and USB-audio:
- More Cirrus HD-audio codec support
- TAS2781 HD-audio codec fixes
- Scarlett2 mixer fixes
Others:
- Enhancement of virtio driver for audio control supports
- Cleanups of legacy PM code with new macros
- Firewire sound updates"

Pull thermal control updates from Rafael Wysocki:
"These mostly change the thermal core in a few ways allowing thermal
drivers to be simplified, in particular in their removal and failing
probe handling parts that are notoriously prone to errors, and
propagate the changes to several drivers.
Apart from that, support for a new platform is added (Intel Lunar
Lake-M), some bugs are fixed and some code is cleaned up, as usual.
Specifics:
- Store zone trips table and zone operations directly in struct
thermal_zone_device (Rafael Wysocki)
- Fix up flex array initialization during thermal zone device
registration (Nathan Chancellor)
- Rework writable trip points handling in the thermal core and
several drivers (Rafael Wysocki)
- Thermal core code cleanups (Dan Carpenter, Flavio Suligoi)
- Use thermal zone accessor functions in the int340x Intel thermal
driver (Rafael Wysocki)
- Add Lunar Lake-M PCI ID to the int340x Intel thermal driver
(Srinivas Pandruvada)
- Minor fixes for thermal governors (Rafael Wysocki, Di Shen)
- Trip point handling fixes for the iwlwifi wireless driver (Rafael
Wysocki)
- Code cleanups (Rafael J. Wysocki, AngeloGioacchino Del Regno)"
