Many Qualcomm clock controller drivers still enable always-on branches
with individual qcom_branch_set_clk_en() calls in their probe functions.
The common probe code already supports describing these register offsets
through the clk_cbcrs and num_clk_cbcrs fields of qcom_cc_driver_data.
Convert the remaining users of these direct calls to per-controller
critical_cbcrs arrays. This centralizes branch enable handling in the
common probe path and makes the always-on register lists easier to review
alongside the other controller data.
For GCC drivers, also describe DFS RCGs through the common driver data and
move auxiliary register programming into clk_regs_configure callbacks
where appropriate. Drivers whose initialization is fully covered by the
common path can then use qcom_cc_probe() directly. Keep device-specific
setup in the remaining probe functions, including the separate CBCR lists
needed by the SA8775P/QCS8300 camera and SM8350/SC8280XP video variants.

Changes in v2:
- Rebased on next-20260923.
- Picked up Konrad's R-b tag for the entire series.
- Use the common alpha PLL configuration handling for GCC SM6375.
- Use regmap_set_bits() for the GPLL0 active-input configuration on SM8250.
- Link to v1: https://patch.msgid.link/20260916-clk-qcom-rework-legacy-always-on-clocks-v1-0-25a24e50f82a@oss.qualcomm.com
