[PATCH v9 14/16] cxl/pci: Remove unnecessary CXL Endpoint handling helper functions

[Terry Bowman <terry.bowman@xxxxxxx>]

The CXL driver's cxl_handle_endpoint_cor_ras()/cxl_handle_endpoint_ras()
are unnecessary helper functions used only for Endpoints. Remove these
functions as they are not common for all CXL devices and do not provide
value for EP handling.

Rename __cxl_handle_ras to cxl_handle_ras() and __cxl_handle_cor_ras()
to cxl_handle_cor_ras().
