Is this really necessary? The COMMON_CLK is only needed for the 
SND_SOC_INTEL_SKYLAKE_SSP_CLK option, isn't it?

and here I would make it a depend. I guess your solution solves the 
compilation but doesn't fully represent the fact that this machine 
driver is not functional without COMMON_CLK+SKYLAKE_SSP_CLK.
