create aud-minimal mode config Our FreeCalypso handset firmware will soon start requiring audio mode configuration files. handfree and headset modes can be omitted on targets that have no headset or loudspeaker support, but the basic handheld mode will always be required - if audio mode loading fails, then volume control via RV Audio Service won't work. The minimal handheld mode config created here should be correct for all currently supported targets.

# The purpose of this audio config table is to make the Iota ABB put the
# downlink audio out at the highest possible output level on EARN&EARP pins,
# to make the quiet speaker as loud as possible.
