[PATCH 0/3] Add extreme platform profile

["Derek J. Clark" <derekjohn.clark@gmail.com>]

This series adds a new "extreme" platform profile mode and uses it for
the lenovo-wmi-gamezone driver. It also prevents bugs that are being
reported by some users by switching the current deny list to an allow
list. Currently there are no validated models, so I've removeed the
unused quirk until something is added to avoid the warning.

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 is stubbed in multiple devices that incorrectly report the
capability as supported. Previously this mode was quirked out for known
problem models, but I've since got multiple bug reports of additional
models that cause issues. Additionally, 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 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 this mode.
