[amlogic] Fixing slow resource initialization

At steady state the stream_control_thread doesn't need much CPU time.
However when doing resource initialization or destruction the thread
finds itself exceeding it's deadline causing the thread to context
switch repeatedly which yields low throughput. To solve this when doing
computational complex operations we use a resource thread which doesn't
have the same restrictive deadline parameters as the
stream_control_thread. However since stream operations are assumed to be
synchronous the stream_control_thread will block on the completion of
those operations.
