Convert the LPASS LPI pinctrl driver to use the PM clock framework for runtime power management. This allows the LPASS LPI pinctrl driver to drop clock votes when idle, improves power efficiency on platforms using LPASS LPI island mode, and aligns the driver with common runtime PM patterns used across Qualcomm LPASS subsystems. Guard GPIO register read/write helpers and slew-rate register programming with synchronous runtime PM calls so the device is active during MMIO operations whenever autosuspend is enabled. Make PINCTRL_LPASS_LPI depend on PM_CLK, since this patch introduces direct PM clock API use in the shared core.
