[Why] Certain configurations of DCN401 require ODM4:1 to support DCC for 10K surfaces. DCC should be conservatively disabled in those cases. The issue is that current logic limits 10K surface DCC for all configurations of DCN401. [How] Add DC ASIC cap to indicate max surface width that can support DCC. Disable DCC if this ASIC cap is non-zero and surface width exceeds it.
