This series adds a new "max-power" platform profile mode and uses it for
the lenovo-wmi-gamezone driver. It also adds the Lenovo Legion Go 2 to
the extreme mode quirks table.

On some Lenovo Legion devices there is a thermal mode called extreme
that corresponds to setting ppt/spl vlaues to the maximum achievable by
the cooling solution. This correlates strongly with an overall power draw
that exceeds the DC power draw capability of the internal battery. This
mode being mapped to performance when extreme mode is detected as
supported, with the actual performance mode being set to
balanced-performance, has led to some misinformation being promulgated
that performance is always a bad setting in Linux for these devices.
There is also some confusion that the mode labeled performance in
userspace, which corresponds to a red LED in Windows, shows as purple
when set using the hardware extreme mode.

I'll also note that as the hard TDP limits are refreshed when on AC or DC
by the ACPI notifier of lenovo-wmi-other method driver, no special handling
of the battery is needed for safety limiting extreme mode.

Thank you for your contribution, it has been applied to my local
review-ilpo-next branch. Note it will show up in the public
platform-drivers-x86/review-ilpo-next branch only once I've pushed my
local branch there, which might take a while.
