iommu/arm-smmu-v3: Manage teardown with devm
In the Linux kernel, the following vulnerability has been resolved: iommu/arm-smmu-v3: Manage teardown with devm arm_smmu_device_remove() manually frees the IOPF queue, destroys the vmid_map and disables the device, while the IRQs and queues are devm managed. devm unwinds only after remove() returns, so the cleanup runs in the wrong order. The IOPF queue is freed before the event-queue IRQ whose handler uses it. Manage all of it with devm so the unwind order is correct. Free the IOPF queue and vmid_map via devm actions, and disable the device from one registered after arm_smmu_device_reset(). This is also a prerequisite for fixing a Tegra241 CMDQV CMD_SYNC use-after-free in the subsequent patch.
