drm/amd/display: For no plane case set pstate support in validation

Browse source

- Previously update_clocks was overriding pstate support if
  it checked that there were no planes
- However, P-State support should be determined in validation
  phase instead
- This fixes an issue where a transition from FPO -> no planes
  expects UCLK MAX, but update_clocks was overriding to set
  UCLK to min
