[PATCH v3 10/11] ARM: Exynos: use fin_pll clock as the tick clock source for mct

[Thomas Abraham <thomas.abraham@linaro.org>]

With the migration of Exynos4 clocks to use common clock framework, the old
styled 'xtal' clock is not used anymore. Instead, the clock 'fin_pll' is used
as the tick clock for mct controller.
