iommu/amd: Move a few prototypes to include/linux/amd-iommu.h
A few functions that were intentended for the perf events support are currently declared in arch/x86/events/amd/iommu.h, which mens they are not in scope for the actual function definition. Also amdkfd has started using a few of them using externs in a .c file. End that misery by moving the prototypes to the proper header.

x86/events/amd/iommu.c: Modify functions to query max banks and counters
Currently, amd_iommu_pc_get_max_[banks|counters]() use end-point device ID to locate an IOMMU and check the reported max banks/counters. The logic assumes that the IOMMU_BASE_DEVID belongs to the first IOMMU, and uses it to acquire a reference to the first IOMMU, which does not work on certain systems. Instead, modify the function to take an IOMMU index, and use it to query the corresponding AMD IOMMU instance.
Currently, hardcode the IOMMU index to 0 since the current AMD IOMMU perf implementation supports only a single IOMMU. A subsequent patch will add support for multiple IOMMUs, and will use a proper IOMMU index.

x86/events/amd/iommu.c: Modify functions to query max banks and counters Currently, amd_iommu_pc_get_max_[banks|counters]() use end-point device ID to locate an IOMMU and check the reported max banks/counters. The logic assumes that the IOMMU_BASE_DEVID belongs to the first IOMMU, and uses it to acquire a reference to the first IOMMU, which does not work on certain systems. Instead, modify the function to take an IOMMU index, and use it to query the corresponding AMD IOMMU instance. Currently, hardcode the IOMMU index to 0 since the current AMD IOMMU perf implementation supports only a single IOMMU. A subsequent patch will add support for multiple IOMMUs, and will use a proper IOMMU index.
