STM32 BDMAv1 driver.
Driver capability:
- The driver supports the "basic" DMA controller.
The file registry must export:
STM32_DMAn_CHx_HANDLER - Vector name for IRQ "x" (1..7). If the macro
is not exported then the ISR is not declared.
STM32_DMAn_CHx_NUMBER - Vector number for IRQ "x" (1..7).
STM32_DMA_CACHE_HANDLING - TRUE if the device requires explicit cache
handling on DMA buffers.
