x64, x2apic/intr-remap: code re-structuring, to be used by both DMA and Interrupt remapping
Allocate the iommu during the parse of DMA remapping hardware definition structures. And also, introduce routines for device scope initialization which will be explicitly called during dma-remapping initialization. These will be used for enabling interrupt remapping separately from the existing DMA-remapping enabling sequence.
