To me, it sounds like you might want to use ->resume_early() or maybe ->resume_noirq() in the pinctrl driver for this so that IO isolation can be disabled sooner?
For calls that need to happen just before the SoC is disabled or first thing on resume path, cpu_cluster_pm_enter() and cpu_cluster_pm_exit() notifiers work nice and allow distributing the code across the related SoC specific code and device drivers. See for example the usage in drivers/irqchip/irq-gic.c for CPU_CLUSTER_PM_ENTER.
