[v7,0/4] Dell AWCC platform_profile support

Message

This patch adds platform_profile support for Dell devices which implement
WMAX thermal interface, that are meant to be controlled by Alienware Command
Center (AWCC). These devices may include newer Alienware M-Series, Alienware
X-Series and Dell's G-Series.

Tested on an Alienware x15 R1.
---
v7:
 - Platform profile implementation refactored in order to efficently
   autodetect available thermal profiles
 - Added GameShiftStatus method to documentation
 - Implemented GameShiftStatus switch for devices that support it 
v6:
 - Removed quirk thermal_ustt.
 - Now quirk thermal can take canonical thermal profile _tables_ defined
   in enum WMAX_THERMAL_TABLES
 - Added autodetect_thermal_profile
 - Proper removal of thermal profile
v5:
 - Better commit messages
 - insize renamed to in_size in alienware_wmax_command() to match other
   arguments.
 - Kudos in documentation now at the end of the file
v4:
 - Fixed indentation on previous code
 - Removed unnecessary (acpi_size) and (u32 *) casts
 - Return -EIO on ACPI_FAILURE
 - Appropiate prefixes given to macros
 - 0xFFFFFFFF named WMAX_FAILURE_CODE
 - Added support for a new set of thermal codes. Old ones now have USTT
   in their names
 - A new quirk has been added to differantiate between the two sets.
   thermal and thermal_ustt are mutually exclusive
 - Added documentation for WMAX interface
v3:
 - Removed extra empty line
 - 0x0B named WMAX_ARG_GET_CURRENT_PROF
 - Removed casts to the same type on functions added in this patch
 - Thermal profile to WMAX argument is now an static function and makes
   use of in-built kernel macros
 - Platform profile is now removed only if it was created first
 - create_platform_profile is now create_thermal_profile to avoid
   confusion
 - profile_get and profile_set functions renamed too to match the above
v2:
 - Moved functionality to alienware-wmi driver
 - Added thermal and gmode quirks to add support based on dmi match
 - Performance profile is now GMODE for devices that support it
 - alienware_wmax_command now is insize agnostic to support new thermal
   methods

Kurt Borja (4):
  alienware-wmi: fixed indentation and clean up
  alienware-wmi: alienware_wmax_command() is now input size agnostic
  alienware-wmi: added platform profile support
  alienware-wmi: WMAX interface documentation
