[PATCH v5 0/2] pinctrl: qcom: lpass-lpi: Switch to PM clock framework

[Ajay Kumar Nandam]

This series converts LPASS LPI pinctrl runtime clock handling to the PM
clock framework and ensures GPIO register accesses runtime-resume the
block before MMIO.

The series is intentionally ordered for bisect safety:
- patch 1 wires runtime PM ops in LPASS LPI variant drivers
- patch 2 updates the shared core to use pm_clk + runtime PM access
  paths and completes sc7280 wiring

After this conversion, LPASS LPI variants sharing the common core use a
consistent DT clock flow via of_pm_clk_add_clks() together with
pm_clk_suspend()/pm_clk_resume() and autosuspend.

Testing:
- Runtime behavior validated on Kodiak (sc7280).
- Wider runtime testing on other LPASS LPI variants is welcome.

---
Changes in v5:
- Send as a proper standalone v5 series with cover letter.
- Fix indentation in newly added .of_match/.pm blocks in:
  sc7280, sc8280xp, sm8250, sm8450, sm8550, sm8650 variants.
- Simplify pm_runtime_put_autosuspend() return handling in
  lpi_gpio_read(), lpi_gpio_write(), and lpi_config_set_slew_rate()
  in the shared LPASS LPI core, per review suggestion.
- No functional changes.
