clk: qcom: gcc-sdx55: Use common clock controller probe data

Browse Source 
Move the always-on branch register offsets into a critical_cbcrs array
and move the register programming into the clk_regs_configure callback.

Use qcom_cc_probe() to perform the common initialization instead of
open-coding it in the driver's probe.
