Split the "amplc_dio200" comedi driver module into separate driver
modules for ISA and PCI boards with a common module for the shared code.
Keep the old name "amplc_dio200" for the ISA board driver as the module
may be modprobed with this name by a script. (If the script uses insmod
it will need modifying to load the "amplc_dio200_common" module first.)
Use the module name "amplc_dio200_pci" for the PCI board driver. On
most systems this will be auto-loaded.
Use the module name "amplc_dio200_common" for the module containing the
shared code. This is normally loaded as a dependency of the other two
modules.
"amplc_dio200_common" exports the following functions:
* `amplc_dio200_common_attach()`: this is basically the old
`dio200_common_attach()` from the combined driver module. It is
called from the driver-specific attach or auto-attach routines.
* `amplc_dio200_common_detach()`: this is most of the old
`dio200_detach()`. It is called from the driver-specific detach
routine.
* `amplc_dio200_set_enhance()`: this is a new function called during
initialization of PCIe cards to enable "enhanced" mode.
