Provide two sorts of interfaces to handle the different use cases:
- msi_domain_alloc_irqs_range():
Handles a caller defined precise range
- msi_domain_alloc_irqs_all():
Allocates all interrupts associated to a domain by scanning the
allocated MSI descriptors
The latter is useful for the existing PCI/MSI support which does not have
range information available.
