Fixed RGB led warnings and error handling
Added include dir for RGB led
Disabled full JTAG port to free PA15 for tone alarm
Fix command registration for modules. 'rgbled test' works now.
Move the LSM303D driver over into the new world.
Share the ROMFS prototype betwen FMUv1 and v2
Fix a misleading comment about the tone_alarm timers.
Fix memory sizing so that we get the extra 64K we promised.
Fix alt function selector for tone_alarm GPIO.
Fix the way that tone_alarm idles the GPIO and make it idle safely for v2 boards.
Fix the v2 RGB LED ID
Add the SoC chip and common directories to the NuttX-related include paths.
Move the FMU driver from the old universe to the new universe so that we can teach it about v2.
Make the 'fmu' command build for v2. Should be enough to get the FMU-side PWM outputs working, but untested.
Add GPIO driver access to the power supply control/monitoring GPIOs for FMUv2
Rename the 'device' directory back to 'drivers', it's less confusing that way.

Move the fmuv2 board driver out into the new world.
Fix the default state of the peripheral power control.
