[v3 03/13] ASoC: intel: mfld-pcm: don't call trigger ops to DSP for internal streams

["Subhransu S. Prusty" <subhransu.s.prusty@intel.com>]

From: Vinod Koul <vinod.koul@intel.com>

For internal stream i.e. BE we have don't need trigger ops as that would be
handled by DAPM for us in subsequent patches
