When the CS35L41 loads its firmware, it has a number of controls to
affect its behaviour. Currently, these controls are exposed as ALSA
Controls.

These controls were never intended to be exposed to users but the
firmware doesn't mark them hidden, so make the driver ignore them.

Any changes in the coefficients handled by these controls needs to
be matched to the individual system by SSID, which is already handled
using the tuning file, when firmware is loaded, so UCM should not be
setting these controls anyway.
