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 guarded
register access paths and adds the PM_CLK Kconfig dependency
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 since v5:
- Rebased to current linux-next and refreshed the shared-core conversion
patch to apply cleanly on top of latest LPASS LPI mux-path updates
- Include SM6350 in the preparatory LPASS LPI per-SoC runtime PM hook
wiring set so all in-tree LPASS LPI variants are covered
- Keep PM_CLK dependency under PINCTRL_LPASS_LPI where shared core PM
clock APIs are introduced
