PCI: remove dynids.use_driver_data
The driver flag dynids.use_driver_data is almost consistently not set, and causes more problems than it solves. It was initially intended as a flag to indicate whether a driver's usage of driver_data had been carefully inspected and was ready for values from userspace. That audit was never done, so most drivers just get a 0 for driver_data when new IDs are added from userspace via sysfs. So remove the flag, allowing drivers to see the data directly (a followon patch validates the passed driver_data value against what the drivers expect).
