The i915 doesn't depend on IOSF_MBI, asm/iosf_mbi.h already defines isof_mbi_* APIs when ISOF_MBI is disabled.
Don't force IOSF_MBI to allow disabling IOSF_MBI for non SoC platforms.

Don't force IOSF_MBI to allow disabling IOSF_MBI for non SoC platforms.
But it is required for Valleyview/Cherryview and we want to support those by default. Tricky. -Chris

If linux kernel is built for Valleyview/Cherryview, ISOF_MBI has to be enabled. The dependency is met there.
