Merge tag 'samsung-cleanup' of git://git.kernel.org/pub/scm/linux/kernel/git/kgene/linux-samsung into next/cleanup

Samsung cleanup for v4.3

- make the following headers local
  watchdog-reset, onenand-core, irq-uart, backlight,
  ata-core, regs-usb-hsotg-phy, spi-core, nand-core,
  fb-core and regs-srom headers
- make the following c file local
  s5p-dev-mfc, dev-backlight and setup-camif c file
- remove keypad-core.h file
- drop owner assignment in pmu.c
- remove duplicated define of SLEEP_MAGIC
- make exynos5420_powerdown_conf() staic

* tag 'samsung-cleanup' of git://git.kernel.org/pub/scm/linux/kernel/git/kgene/linux-samsung:
  ARM: SAMSUNG: remove keypad-core header in plat-samsung
