Fix capture issue with hda codecs. Now the data captured by hda codecs is full of zero. It is caused by mismatch of link dma channel between host and FW. Now host allocates link dma channel at dai config loading stage, and sends it to FW to allocate link dma channel at dai_config function Signed-off-by: Rander Wang <rander.wang@linux.intel.com>

@lgirdwood @plbossart Missing of kernel patch: thesofproject/linux#291 has caused regression topology loading failure on APL and GLL: thesofproject/linux#322 |

@lgirdwood Could you help to revert this PR? We need to make FW master branch work with sof-dev kernel. Next GLK release will be branch out from master next Monday and we need time for more testing on sof-dev kernel and FW master. |

@lgirdwood @mengdonglin 291 is merged, no need to revert 322 |

@RanderWang @lgirdwood Thank you! The merged kernel kernel PR (thesofproject/linux#291) solved the regression. |
