Subject: [PATCH] Add Ficgta01ModemHiddenFeatures class
 I've reworked the enable-echo-suppression-on-dialing-and-accepting.patch
 creating a new class that allow to set all the known hidden modem at commands.
 All this is based on the informations released in the hardware mailing list:
  - http://lists.openmoko.org/pipermail/hardware/2008-August/000451.html
