Stefan Tauner 4b24a2d70b Unify usbdev_status and pcidev_status into dev_entry
Once upon a time usbdev_status was created for the ft2232
programmer. Its IDs are semantically different to pcidev_status
because they indicate USB instead of PCI IDs, but apart from that
both data structures are equal. This change makes life easier for
everything involved in handling and printing the status of devices
that is noted in those structures by combining them into dev_entry.

It is still possible to distinguish between PCI and USB devices
indirectly by using the struct programmer's type field.

Also, add a programmer column to the PCI and USB devices lists.

Corresponding to flashrom svn r1632.
