Some kernel configurations can cause following build error:

Fix this by including <asm/io.h> explicitly.
linux/io.h should be included instead, as checkpatch.pl would suggest.

Also sst-dsp., sst-baytrail-dsp.c and sst-haswell-dsp.c are using memcpy_fromio/_toio but there <asm/io.h> seems to come via
<linux/dma-mapping.h> or <linux/io.h> so I didn't touch them.
