HAL_ChibiOS: separate out DMA allocation for sdcard IO
...
this fixes an issue with DMA to SPI6 on STM32H7. On the H7 SRAM4 can
be used for DMA and BDMA to all devices except for SDMMC which uses
IDMA.
by separating out DMA of sdcard data from other data we can arrange
for DMA to all devices to work

HAL_ChibiOS: avoid doing one-way SPI transfers
...
these transfers use dummy bytes in the hal driver, which may not be in
DMA safe memory, so best to avoid them

HAL_ChibiOS: switch to new bouncebuffer system
...
this removes the dma_flush and dma_invalidate methods and uses a
common bouncebuffer system for all CPU types. This enables microSD
support on STM32F7
