[PATCH v3 4/5] drivers: pinctrl: qcom: sdm845: support GPIO wakeup from suspend

Enable TLMM IRQs to be sensed by PDC when we enter suspend. It is possible that the TLMM may be powered off and not detect GPIOs that are configured as wake up interrupts. By hooking into suspend callbacks, we allow PDC IRQs to take over and wake up the system if wakeup interrupts are triggered.
