In stm32 sdmmc variant revision v3.0, a block gap hardware flow control should be used with bus speed modes SDR104 and HS200. It is enabled by writing a non-null value to the new added register MMCI_STM32_FIFOTHRR. The threshold will be 2^(N-1) bytes, so we can use the ffs() function to compute the value N to be written to the register. The threshold used should be the data block size, but must not be bigger than the FIFO size.
