ASoC: Intel: Atom: fix IOSF_MBI dependency 

fix issue reported by 0-Day with randconfig

The commit a68bc0d43e
("ASoC: Intel: Atom: auto-detection of Baytrail-CR")
added a dependency on IOSF_MBI. The code used the IS_ENABLED macro
to check for this dependency but this is not enough in case the SST
driver is built-in. This could be fixed with IS_REACHABLE but
Baytrail-CR would not be detected depending on combinations of options

Add dependency in Kconfig to solve this for good
