Add this patch just for using the same member(struct regmap *base) in patch 5.

Maybe I should replace syscon_node_to_regmap() with of_iomap() in patch 5.
So that patch 5 will use (void __iomem *base) member, and I also can drop
this patch 3 in this series. 

struct regmap *syscon_node_to_regmap(struct device_node *np);
void __iomem *of_iomap(struct device_node *node, int index);
