The name of cxl_setup_parent_dport() function is not clear, the function
is used to initialize AER and RAS capabilities on a dport, therefore,
rename the function to cxl_dport_init_ras_reporting(), it is easier for
user to understand what the function does. Besides, adjust the order of
the function parameters, the subject of cxl_dport_init_ras_reporting()
is a cxl dport, so a struct cxl_dport as the first parameter of the
function should be better.

cxl_dport_map_regs() is used to map CXL RAS capability on a cxl dport,
using cxl_dport_map_ras() as the function name.
