mmc: dw_mmc: exynos: move the exynos private init
Currently platform specific private data initialization 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 initialization of SMU and etc.
