Currently platform specific private data initialisation is done by dw_mci_exynos_priv_init and dw_mci_exynos_parse_dt.As we already have separate platform specific device tree parser dw_mci_exynos_parse_dt, move the dw_mci_exynos_priv_init code to dw_mci_exynos_parse_dt. We can use the dw_mci_exynos_priv_init to do some actual platform specific initialisation of SMU and etc.
