qcacmn: Remove SCS database from dp_peer structure

Set function pointer for SCS peer lookup and rule handler.

Add a new module id for SCS.

SCS database maintained in dp_peer structure is redundant as
same info is maintained in control peer. Therefore remove
SCS database from dp_peer structure and also remove APIs
which access/update this database.
