AM572x SR1.1 requires different IODelay values to be used than that used in AM572x SR2.0. These values are populated in device tree. Add capability in omap_hsmmc driver to extract IOdelay values for different silicon revision. The maximum frequency is also reduced when using a ES1.1. To keep the ability to boot both revsions with the same dtb, those values can be provided by the platform code.
