mmc: sdhci-esdhc-imx: only enable DAT[0] and CMD line auto tuning for SDIO device
USDHC IP has one limitation: the tuning circuit can't handle the async sdio device interrupt correctly. When sdio device use 4 data lines, async sdio interrupt will use the shared DAT[1], if enable auto tuning circuit to check these 4 data lines, include the DAT[1], this circuit will detect this interrupt, take this as data on DAT[1], and adjust the delay cell wrongly, finally will cause the DATA/CMD CRC error. So for SDIO device, only enable DAT[0] and CMD line for auto tuning. To distinguish the card type during card init, involve init_card().
