Added isDevControllerClass so that XendDomainInfo does not need to store the same information internally.  This may soon go, depending on how useful controller.py turns out to be.

Tiny printk info cleanup.

The attached patch fixes two problems I ran into with the swiotlb code
in unstable (changeset aeaa3c83f6e5). Tested on a dual Opteron x86-64
machine with 4GB of memory and a tg3 modified to only DMA below 2GB.

- swiotlb_dma_supported() checked that the device DMA mask was equal
or bigger than 4GB, when in fact all that's needed is that the device
be able to DMA into the swiotlb aperture (1GB on my AMD x86-64
machine). Some device are actually only 31-bit DMA capable, so this
would've tripped them.

- On some platforms, PCI unmaps and syncs are nops, so there's no need to
keep track of the dma_addr they need after the initial mapping. The
DMA API supports this via the DECLARE_PCI_UNMAP_ADDR macros (see
Documentation/DMA-mapping.txt). Since the swiotlb code does make us of
the dma_addr for swiotlb_unmap_xxx and (more importantly)
swiotlb_dma_sync_xxx, we need to define them to something
meaningful.
