Description

Introduce MSI and MSI-X support to intrng. This adds a new msi device
interface with 5 methods to mirror the 5 MSI/MSI-X methods in the pcib
interface. The pcib driver will need to perform a device specific lookup
to find the MSI controller and pass this to intrng as the xref. Intrng
will finally find the controller and have it handle the requested operation.

Hi, I believe this must be <=

If the MSI range is at the very end of the SPI, you will get start + count == nirqs.
