ASoC: Intel: Load the atom DPCM driver only
DPCM driver is recommended for BYT, CHT based platforms, so if
CONFIG_SND_SST_IPC_ACPI is selected then don't compile the BYT
Device IDs in common ACPI driver to avoid probe conflicts.

which changed the dependencies for CONFIG_SND_SOC_INTEL_BYT_MAX98090_MACH.
The set of options Fedora selects means that
CONFIG_SND_SOC_INTEL_BYT_MAX98090_MACH
can't be selected. Is there another driver that's supposed to replace
CONFIG_SND_SOC_INTEL_BYT_MAX98090_MACH on Bay Trail or do the dependencies
need to be updated? The bugzilla has alsa-info for working and non-
working cases and the Fedora config is attached.

If you remove support for all other baytrail options this driver should still be there and selectable. We just can't support both this driver for Chromebooks and the rest for other machines with the same distribution at the moment.
