add pmu_intmem node for suspend, add global_pwroff pinctrl. The pmu_intmem is used to store the resume code. global_pwroff is held low level at work, it would be pull to high when entering suspend. PMICs can get this signal, then shut down some power rails. So please reference the global_pwroff pinctrl as part of the PMIC config.
