mmc: core: enable CMD19 tuning for DDR50 mode [ Upstream commit 4324f6de6d2eb9b232410eb0d67bfafdde8ba711 ] As SD Specifications Part1 Physical Layer Specification Version 3.01 says, CMD19 tuning is available for unlocked cards in transfer state of 1.8V signaling mode. The small difference between v3.00 and 3.01 spec means that CMD19 tuning is also available for DDR50 mode.
