Similar issues have been seen on the Tegra124 Jetson TK1 and are linked to the UHS-I tuning sequence. Disabling the UHS-I modes for Tegra30 fixes SD card support and prevents any hangs from occurring when entering system suspend. Therefore, disable the UHS-I modes for Tegra30 for now until we can correct the tuning sequence for Tegra.
