The ACPI interface in AMD was a few years out of date
and contained some unused and deprecated functions
Remove functions: Select Active Displays, Get Lid State,
Get TV Standard, Set TV Standard, Get Panel Expansion Mode,
Set Panel Expansion Mode, Get Graphics Device Types
Add functions: Query Backlight Transfer Characteristics,
Ready To Undock Notification
Changed functions: Get System Parameters,
Get System BIOS Requests
All changes are right from the standard
