Log: Set MMC_DATA_MULTI flag when doing multi-block transfers Lower layers (MMC / SDHCI controller drivers) may make certain decisions based on the presence of this flag. The fact that sdhci.c doesn't look at this flag is another problem that should be fixed separately. Found when adding MMCCAM support to AllWinner MMC controller driver where the presence of this flag actually matters.
