qcacld-3.0: Skeleton for DISA component

Create a skeleton for the DISA component. This is a CLD component. Add files for disa core, dispatcher and target_if. Define DISA related public structures and objmgr objects. Add API's as stubs. Change-Id: I63b32a0e7da0283d091815aaccea6b8703f5184c CRs-Fixed: 2159579

+ * !PLEASE READ!
+ *
+ * The following are objmgr navigation helpers for traversing objmgr object
+ * trees.
+ *
+ * Objmgr ensures parents of an objmgr object cannot be freed while a valid
+ * reference to one of its children is held. Based on this fact, all of these
+ * navigation helpers make the following assumptions to ensure safe usage:
+ *
+ * 1) The caller must hold a valid reference to the input objmgr object!
+ *	E.g. Use disa_[peer|vdev|pdev|psoc]_get_ref() on the input objmgr
+ *	object before using these APIs
+ * 2) Given assumption #1, the caller does not need to hold a reference to the
+ *	parents of the input objmgr object
+ * 3) Given assumption #1, parents of the input objmgr object cannot be null
+ * 4) Given assumption #1, private contexts of any parent of the input objmgr
+ *	object cannot be null
+ *
+ * These characteristics remove the need for most sanity checks when dealing
+ * with objmgr objects. However, please note that if you ever walk the tree
+ * from parent to child, references must be acquired all the way down!
+ *
+ * Example #1:
+ *
+ *	psoc = disa_vdev_get_psoc(vdev);
+ *	if (!psoc)
+ *		// this is dead code
+ *
+ * Example #2:
+ *
+ *	psoc_priv = disa_psoc_get_priv(psoc);
+ *	if (!psoc_priv)
+ *		// this is dead code
+ *
+ * Example #3:
+ *
+ *	status = disa_psoc_get_ref(psoc);
+ *
+ *	...
+ *
+ *	psoc = disa_vdev_get_psoc(vdev);
