USB: UHCI: Move PCI specific functions to uhci-pci.c 



This patch is part of a series that extend the UHCI HCD to support
non-PCI controllers.

This patch moves PCI specific functions to uhci-pci.c and includes
this file in uhci-hcd.c. It also renames the function uhci_init to
uhci_pci_init.

uhci_init/uhci_pci_init is modified so that the port-detection logic
is kept in a new separate function uhci_count_ports() in uhci-hcd.c.
