UI fw: load handheld audio mode on boot
We have now reached the point where use of audio mode config files
should be considered mandatory. In ACI usage we can tell users that
they need to perform an AT@AUL of some appropriate audio mode, but
in UI-enabled fw we really need to have the firmware load audio modes
on its own, so that correct audio config gets established when the
handset or development board runs on its own, without a connected host
computer.
Once have FC Venus with both main and headset audio channels and
headset plug insertion detection, our fw will need to automatically
load the handheld mode or the headset mode depending on the plug
insertion state. For now we load only the handheld mode, which has
been tuned for FC-HDS4 on FC Luna.
