bmi3: fixed the mysterious "mute on first call" bug
When UI-enabled fw boots on a previously blank (no /mmi/* files) FFS
for the first time, the output_volume member of the persistent UI settings
structure was left uninitialized, corresponding to the earpiece volume
being set to mute, which is an invalid setting. Because of other quirks
in the far-from-finished UI code, this volume setting takes effect only
when the first call is answered, producing the odd behaviour seen at the
user level.
The current fix is to set the blank-FFS default for output_volume to
volume level 4, which is the same -6 dB Iota volume as the ACI default.
