There is nothing arch specific about PCI or dma-debug, so move this
call to common code just after registering the bus type.

I assume that previously, even if the user set CONFIG_DMA_API_DEBUG=y
we only got PCI DMA debug on powerpc, sh, and x86.  And after this
patch, we'll get PCI DMA debug on *all* arches?

If that's true, I'll add a comment to that effect to the commitlog
since that new functionality might be of interest to other arches.

There should be implicit support for dma-debug for all arches that use
the generic dma_ops code. The dma_debug_add_bus() function just adds the
reporting of pending dma-allocations on driver-unload for a device.
