In the stm32_sdmmc variant, the datatimer is active not only during data transfers with the DPSM, but also while waiting for the busyend IRQs from commands having the MMC_RSP_BUSY flag set. This leads to an incorrect IRQ being raised to signal MCI_DATATIMEOUT error, which simply breaks the behaviour. Address this by updating the datatimer value before sending a command having the MMC_RSP_BUSY flag set. To inform the mmc core about the maximum supported busy timeout, which also depends on the current clock rate, set ->max_busy_timeout (in ms).
