boards: enable NuttX SPI DMA buffers

Browse Source 
- update to NuttX with stm32f4 and stm32f7 SPI DMA internal buffers
 - remove explicit DMA buffer allocations from new IMU drivers
 - restore original BOARD_DMA_ALLOC_POOL_SIZE
 - decrease SPI DMA thresholds based on fmu-v2/v3/v4/v5 bench testing
