ASoC: Intel: avs: dmic: Refactor dai_link creation

To allow for multiple instances of the card, move away from static
dai_link declaration.

While at it, simplify the code as the name of the platform component
matches the name of the card's platform_device:
- drop mach->mach_params.platform usage
- drop snd_soc_fixup_dai_links_platform_name() usage
