ALSA: hda/hda_cs_dsp_ctl: Delete hda_cs_dsp_ctl module

Browse Source 
Delete the hda_cs_dsp module and move the one array and one function
that is used by the cs35l41_hda driver into that driver.

The cs35l41 and cs35l56 drivers stopped creating ALSA controls to
wrap firmware controls. The reasons are explained in:

commit 312c04cee4 ("ALSA: hda: cs35l41: Stop creating ALSA Controls
for firmware coefficients")

and

commit 34e1b1bb73 ("ALSA: hda: cs35l56: Stop creating ALSA controls
for firmware coefficients")

The cs35l56_hda driver now doesn't use hda_cs_dsp_ctl at all. The
cs35l41_hda driver only uses the small array of firmware names and the
function to read a control value. All other functions and data in
hda_cs_dsp_ctl are unused. There is no need to keep a separate module
for such a small amount of data and code that is only used by one driver,
so remove the whole module.
