Merge tag 'remove-nondt-exynos-3' of git://git.kernel.org/pub/scm/linux/kernel/git/kgene/linux-samsung into next/soc

From Kukjin Kim:

cleanup and removing dead code for only support DT for exynos
- remove board file for exynos
- remove legacy files which are not used anymore
- decouple ARCH_EXYNOS from PLAT_S5P

* tag 'remove-nondt-exynos-3' of git://git.kernel.org/pub/scm/linux/kernel/git/kgene/linux-samsung: (35 commits)
  ARM: EXYNOS: Remove remaining dead code after non-DT support removal
  ARM: EXYNOS: Remove legacy L2X0 initialization
  ARM: EXYNOS: Use exynos_init_io() as map_io callback
  ARM: EXYNOS: Remove custom init_irq callbacks
  ARM: EXYNOS: Remove mach/regs-usb-phy.h header
  thermal: exynos: Support both EXYNOS4X12 SoCs
  ARM: EXYNOS: Remove unused base addresses from mach/map.h header
  ARM: EXYNOS: Remove mach/irqs.h header
  ARM: EXYNOS: Select SPARSE_IRQ for Exynos
  ARM: SAMSUNG: Make legacy MFC support code depend on SAMSUNG_ATAGS
  ARM: EXYNOS: Remove mach/regs-gpio.h header
  ARM: EXYNOS: Remove mach/gpio.h
  ARM: EXYNOS: Remove setup-i2c0.c
  ARM: EXYNOS: Do not select legacy Kconfig symbols any more
  ARM: SAMSUNG: Include most of mach/ headers conditionally
  ARM: EXYNOS: Decouple ARCH_EXYNOS from PLAT_S5P
  USB: Check for ARCH_EXYNOS separately
  platform: Check for ARCH_EXYNOS separately
  ARM: SAMSUNG: Compile legacy IRQ and GPIO PM code only with ATAGS support
  ARM: EXYNOS: Provide compatibility stubs for PM code in pm-core.h header
