Subject: [PATCH 3/7] clocksource: Change CPU hotplug priority of exynos_mct
 driver

Exynos Multi-Core Timer driver (exynos_mct) must be started before
ARM Architected Timers (arch_timer), because both timers share common
hardware block and turning on MCT is needed to get ARM Architected
Timer working properly.
