Alexis Bruemmer 1956a96de4 x86 calgary: fix handling of devices that aren't behind the Calgary
The calgary code can give drivers addresses above 4GB which is very bad
for hardware that is only 32bit DMA addressable.

With this patch, the calgary code sets the global dma_ops to swiotlb or
nommu properly, and the dma_ops of devices behind the Calgary/CalIOC2
to calgary_dma_ops.  So the calgary code can handle devices safely that
aren't behind the Calgary/CalIOC2.
