ASoC: SOF: Intel: Baytrail: clarify mutual exclusion with Atom/SST driver

Browse source 
Some distros select all options blindly, which leads to confusion and
bug reports. Since SOF does not support Baytrail-CR for now, and
UCM/topology files are still being propagated to downstream distros,
make SOF on Baytrail an opt-in option that first require distros to
opt-out of existing defaults.

This option is mutually exclusive with the SOF support on
Baytrail/Cherrytrail. If you want to enable SOF on

This adds support for Sound Open Firmware for Intel(R) platforms
using the Baytrail, Braswell or Cherrytrail processors.
Say Y if you have such a device.
This option is mutually exclusive with the Atom/SST and Baytrail
legacy drivers. If you want to enable SOF on Baytrail/Cherrytrail,
you need to deselect those options first.
SOF does not support Baytrail-CR for now, so this option is not
recommended for distros. At some point all legacy drivers will be
deprecated but not before all userspace firmware/topology/UCM files
are made available to downstream distros.
Say Y if you want to enable SOF on Baytrail/Cherrytrail
If unsure select "N".
