ARM: dts: msm: Vote for bus_aggr_clk clock by eMMC and UFS on sdm710

Updated gcc_aggre_ufs_phy_axi_clk clock node in eMMC & UFS device node
with corresponding voter clock node, so that both these drivers can
vote for this clock.

On SDM710, both eMMC & UFS drivers need gcc_aggre_ufs_phy_axi_clk for
their respective functionality. So both the drivers should vote this
clock to ensure this clock is enabled while driver is being accessed.
