clk: qcom: gcc-sdm845: Add the BRANCH_VOTED flag to the GCC GPU clocks

The gcc_ddrss_gpu_axi_clk and gcc_gpu_memnoc_gfx_clk clocks are
controllable from the GPU SMMU clock voting registers. This might
lead them to remain enabled even after removing the SW vote on the
CBCRs.
Changing the halt_check to BRANCH_VOTED takes care of polling the
status bits of these CBCRs only while enabling these clocks.
