The host period bytes value needs to be passed to firmware. However current implementation uses this field for different purpose - to indicate whether FW should send stream position to the host. Therefore this patch introduces another field "no_stream_position", a boolean value aimed to store information about position tracking. This way host_period_bytes preserves its original value.
