This patch fixes a number of issues:
1. IOSF_MBI is only needed for byt-cr detection, which is only supported
on Baytrail/Cherrytrail, move to HiFi2 config

2. SND_SOC_INTEL_SST should not select SND_SOC_INTEL_SST_ACPI, the latter
config is only valid for Haswell/Baytrail legacy but not needed by Skylake

3. SND_SST_IPC_ACPI, used only by the atom/sst driver, should not select
SND_SOC_INTEL_SST, none of the code under common/sst*.c is used

This nesting of configs really makes no sense, it's easier to maintain
if for each platform one can control what is strictly required.

Compiled-tested with each of Haswell, Baytrail legacy, HiFi2, SKL cases
selected independently. 0-day and explicit randconfig tests did not report
additional issues and no functionality loss was observed in Intel tests on
HIFI2 and SKYLAKE platforms
