Subject: [PATCH 2/3] platform/x86: lenovo-wmi-gamezone Use Extreme vice balanced-performance

When upstreaming the gamezone WMI drivers the "extreme" mode was matched
to performance and performance was matched to balanced-performance, but
only when extreme mode was fully enabled. Otherwise performance was
matched to performance. This has led to quite a bit of confusion with
users not understanding why the LED color indicating the platform
profile doesn't match their expectations. To solve this, replace the
confusing convention with the new "extreme" profile.

 For some newer devices the "Extreme Mode" profile is incomplete in the BIOS
