Thomas Gleixner 94ff94cfea genirq/msi: Make MSI descriptor iterators device domain aware
To support multiple MSI interrupt domains per device it is necessary to
segment the xarray MSI descriptor storage. Each domain gets up to
MSI_MAX_INDEX entries.

Change the iterators so they operate with domain ids and take the domain
offsets into account.

The publicly available iterators which are mostly used in legacy
implementations and the PCI/MSI core default to MSI_DEFAULT_DOMAIN (0)
which is the id for the existing "global" domains.

No functional change.
