[PATCH v2 1/3] acpi: platform_profile - Add Extreme profile option

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

Some devices, namely Lenovo Legion devices, have an "extreme" mode where
power draw is at the maximum limit of the cooling hardware. Add a new
"extreme" platform profile to properly reflect this operating mode.
