ASoC: Intel: Skylake: Reset DSP pipe in skl_pcm_hw_free

Currently during destroy pipeline the gateway is disabled
before DMA completion. This leads to improper draining of
data and subsequently causing issues on HD-Audio DMA.
Hence added a new pipe reset IPC in skl_pcm_hw_free in
which the Gateway Enable(GEN bit) is reset to 0 after
DMA completion in skl_pcm_trigger.
