feat(st-sdmmc2): define FIFO size
Instead of using hard-coded values in stm32_sdmmc2_read() function,
use a defined SDMMC_FIFO_SIZE, which is 64 on STM32MP1.

mmc: stm32_sdmmc2: correctly manage block size
DBLOCKSIZE should be filled such as the data size is 2^DBLOCKSIZE.
Hence it is calculated with __builtin_ctz.
