ALSA: hda: hda_cs_dsp_ctl: Add Library to support CS_DSP ALSA controls

Browse source

The cs35l41 part contains a DSP which is able to run firmware.
The cs_dsp library can be used to control the DSP.
These controls can be exposed to userspace using ALSA controls.
This library adds apis to be able to interface between
cs_dsp and hda drivers and expose the relevant controls as
ALSA controls.

[ Note: the dependency of CONFIG_SND_HDA_CS_DSP_CONTROLS Kconfig is
  corrected.  Also, this Kconfig isn't enabled now but will be
  actually enabled in a later patch -- tiwai ]
