mmc: sdhci-esdhc-imx: pdev->id_entry should be immutable
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.
