Adds ADC12 support to MSP430X port.

Adds support for the MSP430X's 12-bit ADC peripheral, as well as
reasonably complete testing of same.

Also includes fixes for several bugs and cleanup of the DMA peripheral,
which used ch calls rather than osal calls and was unclear about what
contexts its methods could be called from.
