A number of laptops have gone to market with old firmware versions that export controls that have since been hidden, but we can't just install a newer firmware because the firmware for each product is customized and qualified by the OEM. The issue is that alsactl save and restore has no idea what controls are good to persist which can lead to misconfiguration.
There is no reason that the UCM or user should need to interact with any of the ALSA controls for the firmware coefficients so they can be removed entirely, this also simplifies the driver.

Changes in v3:
- Remove ability to add firmware coefficients as ALSA controls entirely
Changes in v2:
- v1 was accidentally the backport version for older kernels instead of the one for v6.11
Applied now to for-linus branch. Thanks.
