drm/amd/display: Move mcache allocation programming from DML to resource

Browse Source 
[Why]
mcache allocation programming is not part of DML's core responsibilities.
Keeping this logic in DML leads to poor separation of concerns and complicates maintenance.

[How]
Refactored code to move mcache parameter preparation and mcache ID assignment
into the resource file.
