ASoC: Intel: avs: Adjust platform names

Merge series from Cezary Rojewski <cezary.rojewski@intel.com>:

This series is a direct follow up to the recent
machine-board-registration changes [1]. Initially, a number of smaller
patchsets were part of a bigger block of changes. My attempt to split
them up to make the review easier was unfortunately not successful [2].

The goal of this series is the same one as with [1] - allow for multiple
cards of the same type without workarounds or code duplications.
With the machine-board names being unique - thanks to
PLATFORM_DEVID_AUTO - platform component names shall be adjusted too so
that no misbindings happen.

In essence, majority of the changes can be summarized as: simplifying
card and dai_link initialization. Actions:

- drop mach->mach_params.platform usage
- drop snd_soc_fixup_dai_links_platform_name() usage
- for the probe-board mach-context is dropped entirely. The panic [2] is
  gone
