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.

FreeCalypso Luna phone handset UI development platform consists of these 3 components: * A Caramel-type Calypso motherboard, either iWOW DSK or FC Caramel2 * An LCD carrier board, currently using HaoRan HT020K1QC36S LCD module * A 5x5 keyswitch matrix board for the keypad function This Luna is our primary official platform for FreeCalypso phone handset UI development. The UI code we got from TI comes in two interesting versions: * Big color version: 176x220 pixels, 16-bit color * Small B&W version: originally 84x48 pixels, we are extending it to 96x64 pix (Originally there was also a third version, large 176x220 pix B&W, but we find it uninteresting and we've removed it from our supported set. It was really nothing more than a hack to display a minimal-effort derivative of the original small B&W UI on the large D-Sample LCD, so we are not removing anything of any real substance here.) FC Luna hardware is required for anyone who wishes to work on the phone handset UI project in FC Tourmaline: it is the only target platform that can display both versions of our work-in-progress UI firmware. Mot C1xx and other similar phones have small LCDs that can only display the small B&W version of our TI-based UI, and in the Mother's opinion working solely on the smallbw version to the exclusion of the bigcolor version is not acceptable.
