iommu/amd: Initialize iommu_device->max_pasids

Browse source

Commit 1adf3cc20d ("iommu: Add max_pasids field in struct iommu_device")
introduced a variable struct iommu_device.max_pasids to track max
PASIDS supported by each IOMMU.

Let us initialize this field for AMD IOMMU. IOMMU core will use this value
to set max PASIDs per device (see __iommu_probe_device()).

Also remove unused global 'amd_iommu_max_pasid' variable.
