…git/kgene/linux-samsung into next/dt

From Kukjin Kim:

2nd exynos dt update based on tags/exynos-dt-1
- enable RTC on exynos5250 snow and Arndale boards
- add support LCD and PWM for exynos4210 Origen board
- update bootargs to support 8GiB for exynos5440 SSDK5440 and SD5v1 boards
- enable spi and add opp level for exynos5440
- add example doc for samsung-pinctrl dt bindings
