The AER service driver already includes support for Restricted CXL host
(RCH) Downstream Port Protocol Error handling. 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 Protocol Error handling support will be
added in a future patch.
Limit changes to renaming variable and function names. No functional
changes are added.
