    clk: qcom: camcc-sc7180: Add parent dependency to all camera GDSCs
    
    [ Upstream commit 3e4d179532423f299554cd0dedabdd9d2fdd238d ]
    
    Camera titan top GDSC is a parent supply to all other camera GDSCs. Titan
    top GDSC is required to be enabled before enabling any other camera GDSCs
    and it should be disabled only after all other camera GDSCs are disabled.
    Ensure this behavior by marking titan top GDSC as parent of all other
    camera GDSCs.
