platform/x86: alienware-wmi-wmax: Add support for the "custom" thermal profile

Browse Source 
All models with the "AWCC" WMAX device support a "custom" thermal
profile. In some models this profile signals user-space that the user
wants to manually control the fans, which are always unlocked. In other
models it actually unlocks manual fan control.
