Samsung mach/soc update for v4.10:

1. Minor cleanup in smp_operations.
2. Another step in switching s3c24xx to new DMA API.
3. Drop fixed requirement for HZ=200 on Samsung platforms.

* tag 'samsung-soc-4.10-2' of git://git.kernel.org/pub/scm/linux/kernel/git/krzk/linux:
  ARM: Drop fixed 200 Hz timer requirement from Samsung platforms
  ARM: S3C24XX: Add DMA slave maps for remaining s3c24xx SoCs
  ARM: EXYNOS: Remove smp_init_cpus hook from platsmp.c
