staging: comedi: rtd520: remove 'got_regions' from private data
The 'got_regions' variable in the private data is used as a flag for the detach to know if the pci device has been enabled. Typically the dev->iobase variable is used to indicate this in all the other comedi drivers. Do the same here for consistancy.
