ASoC: Intel: avs: Fix potential integer overflow

Browse Source 
[ Upstream commit c7e832cabe ]

While stream_tag for CLDMA on SKL-based platforms is always 1, function
hda_cldma_setup() uses AZX_SD_CTL_STRM() macro which does:
	stream_tag << 20

what combined with stream_tag type of 'unsigned int' generates a
potential overflow issue. Update the field type to fix that.
