clk: samsung: exynos5420: Add SET_RATE_PARENT flag to clocks on G3D path
Add CLK_SET_RATE_PARENT flag to all clocks on the path from VPLL to G3D,
so the G3D MALI driver can simply adjust the rate of its clock by doing
a single clk_set_rate() call, without the need to know the whole clock
topology in Exynos542x SoCs.
