This lets the user know which DMA has finished.

This does "something" in radio test mode, appearing to generate a
730MHz signal.

altos: Allow STM DMA channels to be reserved for one use2012-04-09T07:05:18+00:00Keith Packardkeithp@keithp.com2012-04-09T07:05:18+00:00urn:sha1:059f09dbca4703c25b42389b54c6510331c39485
This allows a single user of a DMA channel to reserve it for use
without needing to lock the mutex; this is required for DMA from the
ADC to work on megametrum as it wants to start DMA from an interrupt
handler, which cannot block on a mutex.
