The host stream position is updated when no_stream_position is set as 0. However current implementation updates host stream position only when report data is larger than or equal to host period size which is decided by the period size of host side. It maybe cause host stream position update not in time. Therefore this patch introduces another field "cont_update_posn", a boolean value aimed to update host stream position continuously and based on period size of pipeline. It can get better precise when need to update host stream position from firmware.
