audio mode load change from Tourmaline
Our FreeCalypso universe now has two kinds of audio mode config files:
the old 164 byte kind and the new 176 byte kind. We are not enabling
L1_NEW_AEC in Magnetite, only in Tourmaline, thus 164 byte audio mode
files are still native to Magnetite. But we still desire graceful
handling of the situation when a running Magnetite fw may load a
176 byte audio mode file (presumably with new AEC config), thus we
incorporate the same audio mode loading change which we implemented
in Tourmaline: if the loaded audio mode file is of the wrong kind,
the AEC config is cleared to default disabled state.
