new tangomdm build target
TCS211/Magnetite built for target leonardo runs just fine on the Tango-based
Caramel board, but a more proper tangomdm build target is preferable in order
to better market these Tango modems to prospective commercial customers. The
only differences are in GPIO and MCSI config:
* MCSI is enabled in the tangomdm build config.
* GPIO 1 is loudspeaker amplifier control on Leonardo, but on Tango platforms
it can be used for anything. On Caramel boards this GPIO should be
configured as an output driving high.
* GPIO 2 needs to be configured as Calypso input on Leonardo, but on Tango
platforms it can be used for anything. On Caramel boards this GPIO should be
configured as an output, either high or low is OK.
