Note: I think this should return a cycles_t, not an unsigned long.
They're the same (right now), but probably shouldn't be (se

This patch register the exynos mct clocksource as the current timer
as it has constant clock rate. This will generate correct udelay for the
exynos platform and avoid using unnecessary calibrated jiffies. This change
has been tested on exynos5420 based board and udelay is very close to
expected.
