ASoC: Intel: Remove skylake driver

The avs-driver found in sound/soc/intel/avs is a direct replacement to
the existing skylake-driver. It covers all features supported by it and
more and aligns with the recommended flows and requirements based on
Windows driver equivalent.

For the official kernel tree the deprecation begun with v6.0. Most
skylake-drivers users moved to avs- or SOF-driver when AudioDSP
capabilities are available on the platform or to snd-hda-intel
(sound/pci/hda) when such capabilities are not.

For the supported trees the deprecation begun with v5.4 with v5.15 being
the first where the skylake-driver is disabled entirely.

All machine board drivers that consume the DSP driver have their
replacements present within sound/soc/intel/avs/boards/ directory.
