At the moment, the allocation of the mapping may be done when composing the message. However, the composing may be done in non-preemtible context while the allocation requires to be called from preemptible context. A follow-up change will split the current logic in two functions requiring to keep an IOMMU cookie per MSI. A new field is introduced in msi_desc to store an IOMMU cookie. As the cookie may not be required in some configuration, the field is protected under a new config CONFIG_IRQ_MSI_IOMMU. A pair of helpers has also been introduced to access the field.
