mmc: omap_hsmmc: Add support for quirky omap3 hsmmc controller
When device is booted using devicetree, platforms impacted by Erratum 2.1.1.128 is not detected easily in the mmc driver. This erratum indicates that the module cannot do multi-block transfers. Platforms such as LDP which use OMAP3 ES revision prior to ES3.0 are impacted by this. Provide a new compatible property "ti,omap3-pre-es3-hsmmc" to allow driver to determine if driver needs to implement quirks associated with the specific module version (primarily because the IP revision information is not sufficient for the same).
