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.

changes since V3: none
changes since V2: none
changes since V1: none
