ASoC: SOF: ipc: introduce cont_update_posn in sof_ipc_stream_params struct

Browse Source 
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.
