Most peripheral headers simply include <libopencm3/stm32/memorymap.h>
which, like the rest of libopencm3 requires the correct compiler define
flag to be set. A few peripherals were directly including the platform
include, libopencm3/stm32/xx/memorymap.h, and in some of those cases it
wasn't even correctly including the correct platform. (Likely the
result of copy/paste errors)
These direct includes have been eliminated
In the header:
- Fix DMA_SxCR_CT: change shift from 18 to 19
For use with the convenience functions:
- Added DMA_SxCR_CHSEL generic values
- Added DMA_STREAM - generic values
- Added dma_if_offset - rather than separating out LISR and HISR
- Added masks
- Added dma_disable_double_buffer_mode()
