From: Marcin Rajwa <marcin.rajwa@xxxxxxxxxxxxxxx>
In some cases, FW might need use the host_period_bytes even no position
update ipc reqiured from driver, here add another flag for position update,
and preserve host_period_bytes for FW to use.
This might require corresponding FW change and ABI alignment.
