iommu/mediatek: Use correct fwspec in mtk_iommu_add_device()
The mtk_iommu_add_device() function keeps the fwspec in an
on-stack pointer and calls mtk_iommu_create_mapping(), which
might change its source, dev->iommu_fwspec. This causes the
on-stack pointer to be obsoleted and the device
initialization to fail. Update the on-stack fwspec pointer
after mtk_iommu_create_mapping() has been called.
