Gabe Teeger 8424ee7d52 drm/amd/display: eliminate clock manager code duplication 
[Why]
Clock manager contained significant duplicate code between
variants with identical logic for functions using only SMU
calls or shared registers. This increases maintenance overhead
and potential for bugs.

[How]
Expose clock constants and internal functions in header for
sharing. Remove duplicate implementations and update function
pointers to use shared functions. Refactor remaining
variant-specific functions to use shared constants and helper
functions. Add compatibility comments for hardware differences.
