PCI: Add 'override_only' field to struct pci_device_id
Add 'override_only' field to struct pci_device_id to be used as part of
pci_match_device().
When set, a driver only matches the entry when dev->driver_override is
set to that driver.
In addition, add a helper macro named 'PCI_DEVICE_DRIVER_OVERRIDE' to
enable setting some data on it.
Next patch from this series will use the above functionality.

- subvendor and subdevice fields default to PCI_ANY_ID (FFFFFFFF)
- class and classmask fields default to 0
- driver_data defaults to 0UL.
+ - override_only field defaults to 0.
Note that driver_data must match the value used by any of the pci_device_id
entries defined in the driver. This makes the driver_data field mandatory
