crypto: qat - relocate service related functions

Rename (1) is_service_enabled() to adf_is_service_enabled(), and
(2) srv_to_cfg_svc_type() to adf_srv_to_cfg_svc_type(), and move them to
adf_cfg_services.c which is the appropriate place for configuration-related
service logic. This improves code organization and modularity by grouping
related service configuration logic in a single location.
