drm/amd/display: Disable alt-ch until dependencies are ready

Browse source

[Description]
- Alt-Ch cannot be enabled until all dependncies are ready (SMU needs
  to support double p-state + IFWI needs to support G7 regions
  enabled).
- If PMFW enables UCLK DPM without double p-state support and alt-ch
  is enabled then hangs could occur
