ASoC: SOF: Intel: hda: Remove link assignment limitation

Browse Source 
The limitation to assign a link DMA channel for a BE iff the
corresponding host DMA channel is assigned to a connected FE is only
applicable if the PROCEN_FMT_QUIRK is set. So, remove it for platforms
that do not enable the quirk.
