Yes, and my proposal would be to move this dependency where applicable 
in the sound/soc/intel Kconfig. the board-level dependency should only 
be I2C or SPI - or both in some cases, there is no reason to have 
something SoC-dependent at the machine level, and those cases would be 
filtered out anyway.
