The MSIIR register for each MSI bank is aliased to a different
address. The MSI node reg property was updated to contain this
address:
=20
e.g. reg =3D <0x41600 0x200 0x44140 4>;
=20
The first region contains the address and length of the MSI
register set and the second region contains the address of
the aliased MSIIR register at 0x44140.

Why, we should only use one of the register regions.  The second region =
was added to allow for 4k separation and thus PAMU protection.  Not sure =
what listed both regions gets us.
