[PATCH v2 2/3] pinctrl: qcom: lpass-lpi: Enable runtime PM hooks on remaining SoCs

[Ajay Kumar Nandam]

The LPASS LPI core was switched to the PM clock framework and runtime PM,
but only the sc7280 variant driver wired runtime PM callbacks.

Hook up runtime PM callbacks for the remaining LPASS LPI variant
drivers so all SoCs using the common core get consistent pm_clk based
clock handling:
  - sc8280xp
  - sm4250
  - sm6115
  - sm8250
  - sm8450
  - sm8550
  - sm8650

This is a mechanical per-variant driver update that relies on the
same generic PM clock flow (of_pm_clk_add_clks() + pm_clk_suspend/
pm_clk_resume()) and DT-provided clocks.

Runtime behavior was validated on Kodiak (sc7280).
