x86/amd-iommu: Rename iommu_flush_device
This function operates on a struct device, so give it a name that represents that. As a side effect a new function is introduced which operates on am iommu and a device-id. It will be used again in a later patch. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
