Cleanups for the Samsung platforms

Various cleanup changes that the device driver changes are built upon.
Since the samsung cleanups depend on the device tree series, which
depends on the first set of cleanups for tegra.

* tag 'cleanup2' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc:
  ARM: EXYNOS: Use gpio_request_one
  ARM: S5PV210: Use gpio_request_one
  ARM: S3C64XX: Modified according to SPI consolidation work
  ARM: S5PV210: Modified files for SPI consolidation work
  ARM: S5P64X0: Modified files for SPI consolidation work
  ARM: S5PC100: Modified files for SPI consolidation work
  ARM: S3C64XX: Modified files for SPI consolidation work
  ARM: SAMSUNG: Consolidation of SPI platform devices to plat-samsung
  ARM: SAMSUNG: Remove SPI bus clocks from platform data
  ARM: S5PV210: Add SPI clkdev support
  ARM: S5P64X0: Add SPI clkdev support
  ARM: S5PC100: Add SPI clkdev support
