ASoC: Intel: fix SND_SOC_SOF dependencies

[ Upstream commit e837b59f8b411b5baf5e3de7a5aea10b1c545a63 ]

It is currently possible to configure a kernel with all Intel SoC
configs as loadable modules, but the board config as built-in. This
causes a link failure in the reference to the snd_soc_sof.ko module:

Add an optional dependency on SND_SOC_SOF_INTEL_COMMON, to ensure that whenever
the SOF support is in a loadable module, none of the board code can be built-in.

This may be be a little heavy-handed, but I also don't see a reason why one would
want the boards to be built-in but not the SoC, so it shouldn't actually cause
any usability problems.
