PCI: Call dma_debug_add_bus() for pci_bus_type from PCI core

Browse Source 
There is nothing arch-specific about PCI or dma-debug, so call
dma_debug_add_bus() from the PCI core just after registering the bus type.

Most of dma-debug is already generic; this just adds reporting of pending
dma-allocations on driver unload for arches other than powerpc, sh, and
x86.
