[PATCH 4/4] ASoC: Intel: haswell: Mark FE DAIs as nonatomic

PCM operations for DAI links connected with DSP platform component
involve communication with DSP firmware by IPCs. As IPC protocol may
cause thread to sleep while waiting for a response from DSP, propagate
that information to ALSA core by marking all FE DAIs as nonatomic.
