Subject: [PATCH v12 02/25] cxl/pci: Remove unnecessary CXL RCH handling helper functions

cxl_handle_rdport_cor_ras() and cxl_handle_rdport_ras() are specific
to Restricted CXL Host (RCH) handling. Improve readability and
maintainability by replacing these and instead using the common
cxl_handle_cor_ras() and cxl_handle_ras() functions.
