As a good practice, device driver should not modify pdev->id_entry but keep it immutable. Let's assign of_device_id.data with imx_esdhc_type constants directly, so that we do not have to manipulate pdev->id_entry in .probe(). As the result, sdhci-esdhc-imx53 and sdhci-usdhc-imx6q can be removed from platform_device_id table now, since they will only probe from device tree.
