[PATCH 08/74] clockevents/drivers/exynos_mct: Remove unneeded container_of()

[Daniel Lezcano]

From: Alexey Klimov <klimov.linux at gmail.com>

Patch removes unneeded container_of() macro in exynos4_local_timer_setup().
Instead let's pass mevt pointer to setup and stop functions from
exynos4_mct_cpu_notify() and let them get evt pointer.

Tested on odroid-xu3.
