staging: comedi: update adl_pci7296 driver

Currently this driver only supports the 96-channel PCI-7296. The 24 and 48 channel PCI-7224 and PCI-7248 boards share the same register map and just have less 8255 devices providing the i/o channels.

This adds the PCI PnP support for the other boards in the ADLink PCI-72xx series.

Also, remove the legacy attach using the comedi_config utility. This driver now supports the comedi PCI auto config attach mechanism and the legacy attach is not supported or required by this driver.
