    clk: qcom: camcc-x1e80100: Set titan_top_gdsc as the parent GDSC of subordinate GDSCs
    
    [ Upstream commit d9377941f2732d2f6f53ec9520321a19c687717a ]
    
    The Titan TOP GDSC is the parent GDSC for all other GDSCs in the CAMCC
    block. None of the subordinate blocks will switch on without the parent
    GDSC switched on.
