[PATCH 07/12] mfd: syscon: Consider platform data a regmap config name

Use the device platform data as a regmap config
name. This is particularly useful in the regmap
debugfs when there is more than one syscon device
registered, to distinguish the register blocks.

Alternatively I could define a syscon platform data structure,
something like this:

struct syscon_platform_data {
	const char *label;
};
