[PATCH V6 11/18] cxl/region: Rename __create_region() to cxl_create_region()

Currently __create_region() is a static routine used within region.c
So to use it from another file rename it to cxl_create_region().

Later patch will create cxl region after fetching region information
from LSA using cxl_create_region() along with two extra function
parameters.
