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.

FC Tourmaline stdmodem functional configuration is equivalent to Magnetite hybrid. The only intentional diff from Magnetite to Tourmaline in the modem configuration is the change of Nucleus: Magnetite uses the blob version of Nucleus which came with TCS211-20070608, whereas Tourmaline uses the source version of Nucleus by Comrade XVilka. It is essentially a change from an unknown version of Nucleus to a known one, thus it should generally be considered an improvement - but as always with such changes, extensive verification and testing needs to be done in order to ensure that nothing got broken. Aside from the one intentional change of Nucleus version, FC Tourmaline is an entirely new firmware source tree, thus it is always possible that something could have got broken unintentionally, particularly in rarely-tested areas of the firmware. Therefore, extensive testing will need to be done before we can declare Tourmaline stdmodem as officially replacing Magnetite hybrid for stable modem products.
