[ Upstream commit eb78ef4d6f0e51243c1ee117f801dbc503e886ab ]

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.
