ASoC: SOF: Intel: Disable SPIB in non ICCMAX stream

The existing code disable SPIB in the playback direction only because
previously the hda data stream is only used for SOF firmware download
and we prepare capture stream for ICCMAX and prepare playback stream
for non ICCMAX case. But now the hda data stream is also used for
SoundWire BPT which will use both directions. The SPIB is enabled in
non ICCMAX cases and we should disable in clean up.
Add a is_iccmax flag in the hda_data_stream_cleanup() function to align
with the hda_data_stream_prepare() function to enable/disable the SPIB.
