do we need LINUX on this one, it already too long :)
I checked and all include/sound/soc* files have this LINUX_SND_SOC
prefix. I don't mind removing it but then someone will object it's not
consistent.

so the header is just for externs, not a pretty thing, can we avoid these
somehow. Do they need to be in common file, why not keep then in respective
byt/hsw file.
Because they will be shared between drivers, that's the whole point.
I can't put a common table in either of sound/soc/sof or
sound/soc/intel/atom. I didn't find a better solution than a module with
just tables + matching functions in it.

why do you need this change, SND_SOC_INTEL_SST selects
SND_SOC_ACPI_INTEL_MATCH, so we should select top symbol which is
SND_SOC_INTEL_SST
The idea is also to share machine drivers between SOF and closed-source
based platform drivers, so if we keep the semantic of INTEL_SST as is
then it needs to go away from the machine parts.
