The sound/soc/intel/common/sst-acpi.c code only tries to load the

Since these thus will never be used when SND_SST_ATOM_HIFI2_PLATFORM is
enabled, building these drivers when it is enabled is useless.
Add a Kconfig dependency to reflect this, so that SND_SOC_INTEL_BAYTRAIL
cannot be enabled when SND_SST_ATOM_HIFI2_PLATFORM is also enabled.
We had this before and I dropped it when we cleaned the code, mainly since this dependency is one-sided and the selections in menuconfig are a bit odd. It's really a mutual exclusion we'd want.
I think we can get a mutual exclusion by also adding a
depends on SND_SOC_INTEL_BAYTRAIL=n to the SND_SST_ATOM_HIFI2_PLATFORM
Kconfig (this needs testing though), but do we really want
mutual exclusion ? Distros tend to hit 'm' for all these options,
so then we end up with which ever one comes first...
Either way distros are currently building both and that is no good
and since we advice the use of SND_SST_ATOM_HIFI2_PLATFORM making
SND_SOC_INTEL_BAYTRAIL auto-disable seems like a good idea.
