Since commit dbb3d78f ("platform/x86: asus-wmi: Call led hw_changed
API on kbd brightness change"), asus-wmi directly changes the keyboard
LED brightness when the keyboard brightness keys are pressed,
raising the appropriate notification.

However, this notification was unintentionally also being raised during
boot and resume from suspend. This was resulting in userspace showing
the keyboard LED OSD on resume for no good reason.

Move the keyboard LED brightness changed notification
from kbd_led_update to the new kbd_led_set_by_kbd function which is only
called from the keyboard brightness function keys codepath.

The Image Signal Processor found on Cherry Trail devices is brought up in
D0 state on devices which have camera sensors attached to it. The ISP will
not enter D3 state again without some massaging of its registers beforehand
and the ISP not being in D3 state blocks the SoC from entering S0ix modes.

There was a driver for the ISP in drivers/staging but that got removed
again because it never worked. It does not seem likely that a real
driver for the ISP will be added to the mainline kernel anytime soon.

This commit adds a dummy driver which contains the necessary magic from
the staging driver to powerdown the ISP, so that Cherry Trail devices where
the ISP is used will properly use S0ix modes when suspended.

Together with other recent S0ix related fixes this allows S0ix modes to
be entered on e.g. a Chuwi Hi8 Pro and a HP x2 210.

On some Goldmont based systems such as ASRock J3455M the BIOS may not
enable the IPC1 device that provides access to the PMC and PUNIT. In
such scenarios, the IOSS and PSS resources from the platform device can
not be obtained and result in a invalid telemetry_plt_config which is an
internal data structure that holds platform config and is maintained by
the telemetry platform driver.

This is also applicable to the platforms where the BIOS supports IPC1
device under debug configurations but IPC1 is disabled by user or the
policy.

This change allows user to know the reason for not seeing entries under
/sys/kernel/debug/telemetry/* when there is no apparent failure at boot.

The original asus-wmi queues a work which calls the ACPI/WMI methods to
update the keyboard LED brightness.  Similar drivers - acer-wmi,
dell-wmi-led just call the ACPI/WMI methods directly without workqueues.

This patch simplifies the keyboard brightness updating process which
calls the kbd_led_update function directly without workqueue in

Some users have been reporting issues with thunderbolt being turned off
before fully initialized. This is suspected to be caused by userspace

https://github.com/hughsie/fwupd/commit/c07ce5b4889a5384

To allow easier debugging of this situation add output that can be turned
on with dynamic debugging to better root cause this problem.
