platform/x86/amd/pmf: Store commonly used enums in the header file

Relocate commonly used enums from multiple source files into a shared
header file to simplify code structure, improve readability, and
enhance maintainability. Also, remove the initialization of the first
enum member, since it is not needed.

Add the AMD_PMF_ prefix to the laptop_placement and platform_type enums
since these names are overly generic for inclusion in a UAPI header
