clk: qcom: gcc: Make gcc_ddrss_gpu_axi_clk as always ON

If GPU CX GDSC was left enabled before HLOS bootup, GDSC fails
to disable after HLOS boots up as some transactions are observed
between GPU and GEMNOC. To avoid this GPU CX GDSC disable failure,
mark gcc_ddrss_gpu_axi_clk as always on as per the HW suggestion.
