ARM: EXYNOS: Initialize the clocks prior to timer initialization
Since the clock initialization should be completed prior to the mct
timer initialization, create a new function 'exynos_init_time' that
first sets up the clock and then invokes the timer initialization
function. The 'init_time' callback in the board files are updated to
invoke this new wrapper function.
