[PATCH] mmc: meson-mx-sdio: trigger a soft reset after a timeout or CRC error

The vendor driver (from the 3.10 kernel) triggers a soft reset every time before starting a new command. While this fixes a problem where SDIO cards are not detected at all (because all commands simply timed out) this hurts SD card read performance a bit (in my tests between 10% to 20%). Trigger
