Process and handle alsa controls map
Process and handle alsa controls map by : Parse and store info from 'halmap' section into a structure. If the hal is available : - Test if controls are available (if use of existing control). - Create new controls (if use of control to create). - Add a verb for each element of the section. - Handle call to alsa when a verb request is detected. - Resgister to event from this device. - Handle call to action if event on this control is detected. Change-Id: I246e16e9d02e64a1778f5c78d2458a33bdfb6d7e Signed-off-by: Jonathan Aillet <jonathan.aillet@iot.bzh>
