clocksource: Exynos_mct: Use irq_force_affinity() in cpu bringup
commit 30ccf03b4a6a2102a2219058bdc6d779dc637dd7 upstream.
The starting cpu is not yet in the online mask so irq_set_affinity()
fails which results in per cpu timers for this cpu ending up on some
other online cpu, ususally cpu 0.
Use irq_force_affinity() which disables the online mask check and
makes things work.
