Explicitly use enum for dma_channel, instead of ints (since channel is
1-based in the docs and 0-based in the enum). Add enum values for
other channels like USART.
Use volatile structs instead of typecasting through REG32().
Other assorted code cleanup.
Remove DMA2 partial support, since neither STM32F100R8 nor STM32L151x
has hardware support for it and it cluttered the code.
No functional changes.

There's no need for it to be initalized in board_init(); it just needs
to be done before ADC / I2C / SPI initialize.
