HAL_ChibiOS: avoid an issue with DCache init on H743
...
this fixes an issue found by Andy Piper where the H743 bootloader gets
a hard fault in the DCache enable code when SRAM1 is primary memory.
This is the simplest fix I could think of, and avoids the problem by
making DTCM the first segment in the bootloader.
Note that we can't use DTCM as first segment for main firmware since
we went to double precision EKF as the static variables don't fit

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
