Merge branch 'samsung/cleanup' into next/cleanup
From Kukjin Kim:
Here, there are cleanup patches for Samsung v3.7 and most of them are
related to cleanup Samsung specific gpio API.
* samsung/cleanup:
gpio: samsung: Update documentation
ARM: S3C24XX: Use module_platform_driver macro in mach-osiris-dvs.c
ARM: S3C24XX: Use module_platform_driver macro in h1940-bluetooth.c
gpio-samsung: Remove now unused s3c2410_gpio* API
ARM: S3C24XX: Remove obsolete GPIO API declarations
ARM: S3C24XX: Convert users of s3c2410_gpio_setpin to gpiolib API
ARM: EXYNOS: cleanup unused code related to GPS
