[ALSA] caiaq - add control API and more input features
- added support for all input controllers on Native Instrument's 'Kore
controller'.
- added ALSA controls to switch LEDs on 'RigKontrol 2', 'RigKontrol3',
'Audio Kontrol 1' and 'Kore controller'.
- added ALSA controls to switch input mode, software lock and ground
lift features on 'Audio 8 DJ'.
