ASoC: SOF: ipc: introduce no_stream_position in sof_ipc_stream_params struct
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.
