commit 2265098fd6a6272fde3fd1be5761f2f5895bd99a upstream.
Timing Information in Datasheet assumes that HIGH_SPEED_ENA=1 should be set for SDR12 and SDR25 modes. But sdhci_am654 driver clears HIGH_SPEED_ENA register. Thus, Modify sdhci_am654 to not clear HIGH_SPEED_ENA (HOST_CONTROL[2]) bit for SDR12 and SDR25 speed modes.
