x86/events, drivers/iommu/amd: Introduce amd_iommu_get_num_iommus()

Introduce amd_iommu_get_num_iommus(), which returns the value of
amd_iommus_present. The function is used to replace direct access to the
variable, which is now declared as static.

This function will also be used by AMD IOMMU perf driver.
