clk: msm: clock-gcc: Associate gfx rail voting with gfx3d branch 



The root clock of gfx3d_clk_src is required to be voted on before enabling
the oxili gdscr and disabled after disabling gdscr. GFX rail can not handle
any voltage set from clk_disable_unprepare after disable of gdscr, thus
moving the rail voting with the gfx3d branch.
