Enabling DM_MMC is forcing CONFIG_BLK=y so if any board which uses SCSI must need to enable DM_SCSI otherwise SCSI reads on that particular target making invalid reading to the disk drive.
Allwinner platform do support SCSI on A10, A20 and R40 SoC's out of these only A10 have DM_SCSI enabled. So enabling DM_MMC on A20, R40 would eventually end-up with scsi disk read failures like [1]
So, enable DM_MMC in all places of respective SoC's instead of enabling them globally to Allwinner platform.
Now, DM_MMC is enabled in Allwinner SoC's except A20 and R40.
