soc/amd: factor out ACPI ALIB function numbers to common code 

The ACPI ALIB function numbers are defined in the AMD Generic
Encapsulated Software Architecture (AGESA™) Interface Specification
(document #55483).

TEST=Timeless build stays the same for Mandolin (Picasso) and Gardenia
(Stoneyridge).
