During probe if the regulator could not be enabled, the error exit path
would still disable it. This could lead to unbalanced counter of
regulator enable/disable.

The patch moves code for getting and enabling the regulator from
exynos_map_dt_data() to probe function because it is really not a part
of getting Device Tree properties.
