[PATCH 23/42] mmc: exynos_dw_mmc: Use .of_to_plat for device tree parsing

[Sam Protsenko]

exynos_dwmci_get_config() is called from the probe function and used to
read data from device tree. Make use of .of_to_plat driver callback
instead, and convert exynos_dwmci_get_config() to match its signature.

No functional change.
