[PATCH 2/8] Consolidate all .h lines at front of intel-iommu.c file

[Bill Sumner]

 In intel-iommu.c, move downward the few lines near the
 front that should not move to an intel-iommu-private.h
 file (mostly data-item definitions) This leaves a
 consolidated block of the lines that would move to an
 intel-iommu-private.h file at the front of the file.
