Merge series "ASoC: soc-compress: tidyup STREAM vs COMPRESS" from Kuninori Morimoto <kuninori.morimoto.gx@renesas.com>:

Hi Mark

These are v2 of tidyup patch-set for SNDRV_PCM_STREAM_xxx and SND_COMPRESS_xxx.
soc-compress is using both SNDRV_PCM_STREAM_xxx and SND_COMPRESS_xxx, but mixed use.
This is confusable, but no problem. Because these are defined as UAPI and
are using same value.
This patch-set make sure these are same value.

v1 -> v2
	- checks COMPRESS vs PCM_STREAM by using BUILD_BUG_ON()
