No functional change. Renamed the *host* directory present inside
drivers/pci to *controller*. Some of the controllers present in
drivers/pci/host is capable of operating in endpoint mode.
So having these drivers in *host* directory might not be appropriate.
This is in preparation for adding endpoint mode support for some of
controller drivers present here.

This is a big and painful change.  I'd suggest to either drop it for
now or convince Bjorn to take it as a scripted renamed just after -rc1.
