[PATCH 2/8] ASoC: Intel: avs: Relocate HDA BE DAI specific operations

[Cezary Rojewski <cezary.rojewski@intel.com>]

DAI's startup()/shutdown() shall deal with allocation and freeing of
resources needed to facilitate streaming over it. Currently for HDAudio
BE DAIs some of that task is done in component->open()/close(). Relocate
the relevant pieces to address that.
