Subject: [PATCH] clk samsung exynos5420 add CLK_RECALC_NEW_RATES flag to mout_apll and mout_kpll clock.

Addition of CLK_RECALC_NEW_RATES flag to support Exynos5 cpu clk so that
correct divider values are re-calculated after both pre/post
clock notifiers had run for for mout_apll clock and mout_kpll clock.

Depend on https://lkml.org/lkml/2015/4/3/388

Tested on OdroidXU3 Board.
