iommu: Allow PCI to use IOMMU infrastructure
This patch adds some hooks to let PCI devices and busses use the new IOMMU infrastructure. When IOMMU support is enabled, each PCI device now contains a DMAContext * which is used by the pci_dma_*() wrapper functions. By default, the contexts are initialized to NULL, assuming no IOMMU. However the platform or host bridge code which sets up the PCI bus can use pci_setup_iommu() to set a function which will determine the correct DMAContext for a given PCI device. Cc: Michael S.
