ASoC: SOF: Intel: Baytrail: fix 'defined but not used' warnings

Browse Source 
With the allmodconfig option, CONFIG_SND_SOC_SOF_BAYTRAIL is disabled
due to mutual exclusion with the legacy driver. This generates
'defined by not used' warnings.

suspend/resume/remove are only supported for Baytrail for now, so move
the code under the CONFIG_SND_SOC_SOF_BAYTRAIL checks.
