Changes in v5:
 - Cleaned up MT8186 soundcard migration commit which erroneously
   had leftovers from development
 - Changed the mtk_pcm_constraints_data structure to hold pointers
   to snd_pcm_hw_constraint_list, as to really reuse the const data
 - Tested again on all of the listed MTK platforms.

Changes in v4:
 - Rebased over next-20240409
 - Dropped the first 4 patches from v3 as were already picked by Mark
 - Fixed W=1 build issue

Changes in v3:
 - Added audio-routing names in enum in all yaml files
 - Added mention of disallowing old and new properties together in
   commit message of bindings patches
 - Fixed validation errors with sound-card-common.yaml inclusion
   due to missing model property in examples
 - Removed `else` enforcing headset-codec/speaker-codecs requirement
   if xxx-dai-link not present to avoid future commit noise as the
   deprecated statement will disallow deprecated properties as required

Changes in v2:
 - Bindings: Changed link-name/codec/clk-provider to remove `items`
   and leave just the enum
 - Moved .*-dai-link pattern additionalProperties after `type: object`
 - Added ref to sound-card-common.yaml
 - Fixed dai-link-xxx -> xxx-dai-link typo in example comment

This series performs a cleanup of most of the MediaTek AFE drivers and
soundcard machine drivers, reducing code duplication and setting a base
to be consistent with their devicetree bindings, as many of those are
using different properties and nodes for no good reason.

Summarizing:
 - Commonizes functions and ops where possible
 - Adds a common probe mechanism, increasing maintainability of
   soundcard drivers for older MediaTek SoCs
 - Migrates all drivers to support the new bindings
   - Obviously retains compatibility with old device trees
 - Reduces machine-specific parameters hardcoding in drivers
   - Can now set machine-specific params in device tree
   - Uses the `audio-routing` and `dai-link` nodes like some
     other non-MediaTek SoC sound drivers
 - Imposes consistency between MediaTek ASoC machine soundcard
   drivers bindings
 - Reduces code size and greatly reduces the amount of code that
   will be required for newer drivers (retaining compatibility with
   the old bindings was costly in terms of code size, otherwise
   this series would've removed ~1000 more lines, or something
   along that line).

This series was (manually) tested on MT8173, MT8192, MT8195 and MT8186
Chromebooks.
