The current implementation is based on CXL1.1 using a root complex event collector. Rename function interfaces and parameters where necessary to include virtual hierarchy (VH) mode CXL PCIe Port error handling alongside the RCH handling.[1] The CXL PCIe Port error handling will be added in a future patch. Limit changes to renaming variable and function names. No functional changes are added.
