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
