iommu/amd: Add NUMA node affinity for IOMMU log buffers
Currently, PPR Log and GA logs for AMD IOMMU are allocated using
iommu_alloc_pages_sz(), which does not account for NUMA affinity. This can
lead to remote memory access latencies if the memory is allocated on a
different node than the IOMMU hardware.
Switch to iommu_alloc_pages_node_sz() to ensure that these data structures
are allocated on the same NUMA node as the IOMMU device. If the node
information is unavailable, it defaults to NUMA_NO_NODE.
