drm/amd/display: Move PME to function pointer call semantics

Browse Source 
[why]
Legacy IRI style is not linux friendly.

[how]
New function pointer call
semantics will be used for all future PPLIB/DAL interfaces, and also
some existing will be refactored.  This change defines how the
new function pointer structures will look, as well as implements
