Subject: [PATCH] ASoC: SOF: ipc: introduce no_stream_position in sof_ipc_stream_params struct
Git-commit: e3ebfd0ab5b4880bfb6a9f32614c2e389cc3da56
Patch-mainline: v5.5-rc1
References: jsc#SLE-16518

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.
