clk: qcom: gpucc-sar2130p: Use common probe handling for always-on clocks

Browse Source 
Describe the always-on branches in a critical_cbcrs array and reference
it through qcom_cc_driver_data. Let qcom_cc_really_probe() enable these
branches instead of programming them directly in the driver's probe.
