Because the gpio-samsung.c can replace old Samsung GPIO drivers. Basically, the gpio-samsung.c has been made by their merging and removing duplicated definitions. Note: gpio-samsung.c includes some SoC dependent codes and it will be replaced next time.

Basically the samsung_xxx prefix is used in gpio-samsung.c instead of s3c_xxx, because unified name can reduce its complexity. Note: some s3c_xxx stil remains because it is used widely. It will be updated next time.
