I just copied the logic from few lines above where we handle PCI init.
I guess the point was to support other host devices even is PCI host
registration fails.

This is something I don't understand. This PCI bridge was also always
confusing me.
Why do we want a separated file for that? What's wrong with having 1
file for host (PCI/PCMCIA) driver (probe and remove functions) *and*
ssb initialization?
