drm/amd/display: Update dcn60 clkmgr interfaces

Browse source

[Description]
Update clk_mgr interfaces to match with the DAL<->PMFW
message interfaces for DCN6.
- dalsmc.h MAX_PPCLK_COUNT must match PPCLK count in driver_if header
- include driver_if header as a local copy for now since PMFW carried one
  will not build
- clk table returned by PMFW is in Khz, must convert to Mhz accordingly
- boot snapshot for dispclk is in Khz
- Get*Clk interfaces should return frequency in Khz, ensure that DAL
  interfaces are implemented to handle this
- Move structure definitions into dcn60_clk_mgr_smu_msg.h header since
  the official dalsmc.h header does not carry all these definitions yet
