Terry Bowman b3741ac86c cxl/pci: Change CXL AER support check to use native AER ... Native CXL protocol errors are delivered to the OS through AER reporting. The owner of AER owns CXL Protocol error management with respect to _OSC negotiation.[1] CXL device errors are handled by a separate interrupt with native control gated by _OSC control field 'CXL Memory Error Reporting Control'. The CXL driver incorrectly checks for 'CXL Memory Error Reporting Control' before accessing AER registers and caching RCH downport AER registers. Replace the current check in these 2 cases with native AER checks.
