Pull iommu fix from Will Deacon:
 "Fix interrupt table length definition for AMD IOMMU.

  It's actually a fix for a fix, where the size of the interrupt
  remapping table was increased but a related constant for the
  size of the interrupt table was forgotten"

* tag 'iommu-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux:
