audio: Set Analog and HDMI mixer controls

Set Analog and HDMI mixer controls for db845c
on boot completion using tinymix.

Put a 1 second sleep in-between pd-mapper and
tinymix to let sound/codecs initialized properly
before setting mixer controls. Also made sure
that audio out interface is ready before
audioserver service get started.
