arch/arm/src/stm32h7/stm32_sdmmc.c: Fixes for IDMA transfer and cache usage

Browse Source

This simplifies the sdmmc driver when the IDMA is in use. There is no need to mix
IDMA and interrupt based transfers; instead, when making unaligned data tranfers,
just make IDMA into an internal aligned buffer and then copy the data.
