We introduce two new enum values for the irq domain flag: - IRQ_DOMAIN_FLAG_MSI indicates the irq domain corresponds to an MSI domain - IRQ_DOMAIN_FLAG_MSI_REMAP indicates the irq domain has MSI remapping capabilities. Those values will be useful to check all MSI irq domains have MSI remapping support when assessing the safety of IRQ assignment to a guest. irq_domain_hierarchical_is_msi_remap() allows to check if an irq domain or any parent implements MSI remapping.
