The first patch corrects an issue when parsing the sg list to check DMA
constraints.
The second patch manages those DMA alignment by copying from or to a
bounce buffer, the way it is done in meson-gx-mmc.

mmc: mmci: stm32: correctly check all elements of sg list
mmc: mmci: stm32: use a buffer for unaligned DMA requests
