soc: samsung: Add exynos chipid driver support Exynos SoCs have Chipid, for identification of product IDs and SoC revisions. This patch intends to provide initialization code for all these functionalities, at the same time it provides some sysfs entries for accessing these information to user-space. This driver uses existing binding for exynos-chipid.
