qcacmn: Add CE services changes for SRNG based target
SRNG based target uses SRNG(Standard Ring) interface to implement all
the ring related access functions. This change provides CE services to
use interact with SRNG for CE access. It uses hal_srng module for HW
related access. It implements src ring using SRNG src ring and
destination ring using dest and status ring.
fastpath and batch send is not implemented as these are not applicable
to this target
