iommu/amd: Set DTE[IntTabLen] to represent 512 IRTEs
According to the AMD IOMMU spec, the commit 73db2fc595f3
("iommu/amd: Increase interrupt remapping table limit to 512 entries")
also requires the interrupt table length (IntTabLen) to be set to 9
(power of 2) in the device table mapping entry (DTE).
