Ajay Kumar Nandam b719ede389 pinctrl: qcom: lpass-lpi: Switch to PM clock framework for runtime PM ...

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.
