ASOC: SOF: Intel: hda-dai: consistent naming for HDA DAI and HDA link DMA 

The Intel documentation refers to the concepts of 'HDAudio host
DMA' (system memory <--> DSP) and 'HDaudio link DMA' (DSP <-->
peripherals). We currently use the prefix 'hda_link' to describe DAI
operations, which can be confused for dailink operations.

Since the topology tokens refer unambiguously to the 'HDA' dai, let's
drop the link prefix for dai-related ops/callbacks. Conversely let's
use 'hda_link_dma' for routines related to the DMA management. In a
follow-up patch we will introduce the 'hda_dai_link' prefix for dailink
ops/callbacks.
