drm/amd/display: Dump clock registers in HW init instead of SW init

Browse source

[Why & How]
- Dumping clock registers in SW init can get incorrect clock readback due
  to other init code (e.g., in DMU) potentially not executed yet
- Move clk_ip register access into HW init to ensure the clock read back
  gets the correct values
