ASoC: Intel: boards: fix randconfig issue

on x86_64:

ERROR: modpost: "sof_dai_get_bclk"
[sound/soc/intel/boards/snd-soc-intel-sof-cirrus-common.ko] undefined!

ERROR: modpost: "sof_dai_get_mclk"
[sound/soc/intel/boards/snd-soc-intel-sof-realtek-common.ko]
undefined!

This comes from a missing dependency on at least ONE SOF platform
being selected. This dependency exists for all other machine drivers,
this was missed in the earlier reviews.

Fixes: 2fe14ff6 ("ASoC: Intel: sof_ssp_amp: rename driver and support cs35l41 amplifier")
