clk: qcom: gpucc-lahaina: Fix gpu_cc_cx_gmu_clk stuck off warning

Earlier gpu_cc_cx_gmu_clk, gpu_cc_hub_cx_int_clk are kept always on,
due to SMMU hw voting missed tying these 2 clocks.
Update gpu_cc_cx_gmu_clk flag to CLK_DONT_HOLD_STATE as this clk
is used with aon ops and should not be warned by clk framework as clk
hold off state during the kernel boot.
