This series adds the MCPM backend support for SMP secondary boot and core
switching on Samsung's Exynos5420. The patches are based on the mcpm
support added for Exynos5420 in the Chromium kernel repository here:
https://chromium.googlesource.com/chromiumos/third_party/kernel-next/+/chromeos-3.8

This patchset depends on:
ARM: EXYNOS5: Add PMU settings for exynos5420
(https://patchwork.kernel.org/patch/3896471/)

The patches have been prepared on Kgene's for-next branch and tested on
SMDK5420 EVT1 using the "/dev/b.L_switcher" user interface.
