However, there are device models which use different MMIO ops: TYPE_IMX_USDHC uses usdhc_mmio_ops and TYPE_S3C_SDHCI uses sdhci_s3c_mmio_ops. Forcing sdhci_mmio_le_ops breaks SD card handling on the "sabrelite" board, for example. Fix this by defaulting the io_ops to little endian and switch to big endian in sdhci_common_realize() only if there is a matchig big endian variant available.
