svn commit: r299370 - head/sys/arm64/cavium

[Andrew Turner]

Author: andrew
Date: Tue May 10 15:45:59 2016
New Revision: 299370
URL: https://svnweb.freebsd.org/changeset/base/299370

Log:
  Push the logic to talk with the MSI/MSI-X interrupt controller to the FDT
  attachment. This is where it will live when we import intrng as it will
  need to look at either the msi-parent or msi-map FDT properties.
