cpu/stm32: avoid deadlock on nonblocking write
...
If a write to a full tsrb is attempted with disabled interrupts
or in a interrupt then a deadlock will occure. To avoid this make
space in the ringbuffer by synchrnously writing to uart.

stm32/spi: Reduce register writes in hot path
...
This combines a number of register writes in the SPI
acquire and transfer code. The DMA enable for SPI is moved to the
acquire function, switching between DMA and regular transfer between
acquires is not possible.

stm32/dma: add setup and prepare functions
...
This commit adds two new functions to the DMA peripheral code for the
stm32. The setup function allows for a one-time setup of peripheral
config. The prepare function does the per-transfer setup. This allows
for a single setup call during the peripheral lock step and a
per-transfer call to the prepare function.
