From Kukjin Kim:
Samsung fixes for v3.11
- fix kernel booting on exynos5440
  skip pm which is not supported
  update regarding LPAE features
- fix s3c2440 uart with adding clkdev entries
- fix compilatioin for Samsung SoCs with selecting pm
- update ARCH_NR_GPIO to support exynos4412 has more gpios
