Pirelli DP-L10 support, steve-m/testing branch

Hi all, last weekend I have grinded down a DP-L10 pcb and traced the TSPACT wiring of this board. I've added support for this phone, along with a few other changes in my branch steve-m/testing. Changes include: * Add support for Pirelli DP-L10 * Add TX support for the gta0x devices * separate board images for the Compal E86 (Motorola C139/C140) (display/keypad backlight now works by default) If anyone wants to test those changes (especially the freerunner TX support, since I have no freerunner), please feel free to do so. I tested the other changes and didn't find any regressions, so if no one else does, we can merge it to master soon. One thing I noticed during testing: The C139/C140 seem to have a different SYSTEM_INHERENT_GAIN, I compared the RX levels of several C118/C123/C155 with several C139/C140, and the reported rx level was always at around 18-20dBm worse than with the C123. Regards, Steve
