ANDROID: topology: Add flag to indicate topology has been updated

Browse Source 
Commit f7128c75332b ("ANDROID: sched: Add vendor hooks for update_topology")
was intended for the modules to get informed when topology
initialization had completed.

However that is not sufficient, the module could be insmoded after
the hook was invoked.

For such situations create a flag for modules to detect that topology
initialization is completed.
