[PATCH] 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). Fixes: 73db2fc595f3 ("iommu/amd: Increase
