Subject: [PATCH v2] mmc: dw_mmc: Add MSHC compatible for Exynos4412

This patch adds the compatible string for MSHC controller of Exynos4412, and
share the controller specific properties with Exynos5250 since they have same
features. Its driver data name is changed to exynos5_drv_data not to use SoC
specific name.
