When attaching a PCI device manually via the comedi driver `attach` hook
(`das08_attach()`) (called by the comedi core for the `COMEDI_DEVCONFIG`
ioctl), its reference count is incremented in the `for_each_pci_dev`
loop (in `das08_find_pci()`). It is decremented when the `detach` hook
(`das08_detach()`) is called to detach the device. However, when the
PCI device is attached automatically via the `attach_pci` hook
(`das08_attach_pci()`, called at probe time via
`comedi_pci_auto_config()`) it's reference count is not incremented so
there will be an unmatched decrement when detaching the device.
Increment the PCI device reference count in `das08_attach_pci()` to
correct the mismatch.
Once support for manual configuration has been removed from this driver,
the calls to `pci_dev_get()` and `pci_dev_put()` can be removed.

This boardinfo for this driver is unneccesary. This driver is only
for testing the comedi subsystem. It defines two dummy subdevices,
an 8 channel analog input subdevice and an 8 channel analog output
subdevice. There is no "board" associated with it.
Remove the boardinfo to keep the driver simple.

The only field in the boardinfo for this driver is a pointer to the
board 'name'. This field is used by the comedi core to match against
the driver when doing a legacy attach. If a driver does not have any
boardinfo, the comedi core matches against the driver name.
Since the boardinfo name and driver name are identical we can simplify
this driver a bit bu just removing the boardinfo completely.

Add the analog input and analog output only versions of the card
to the boardinfo. These cards all share the same i/o map.
Cleanup the attach so that the unsupported subdevices are not
initialized.
All of these boards also have an 8254 counter/timer. The 8254
device is not currently supported but stub in the subdevice
information so it can easily be added.

Currently the 'detach' function in this driver walks thru the
boardinfo in order to find the subdevice index for any sdio
subdevices in order to call the subdev_8255_cleanup(). Then
it goes thru all the subdevices to clean the s->private pointer.
All the sdio subdevices are unique in that the s->type is
COMEDI_SUBD_DIO. Use that to know when to call the cleanup
for the 8255 subdevice.

Only one 'reset' of the card is required in the attach. Remove the
one before setting up the subdevices and leave the one before
exiting the attach function.
The 'valid' variable in the private data is not needed. This variable
is used in the detach to determine if it's ok to call the 'reset'
function. Checking if dev->iobase is valid works just as well.

The devpriv macro relies on a local variable having a specific name.
Remove it.
The this_board macro in this driver is a bit different in this driver.
In other comedi drivers, this macro returns the dev->board_ptr. In this
driver its simply 'boardtypes' which returns the first boardinfo element.
Remove this macro also by making sure the dev->board_ptr is set in the
pci1723_find_pci_dev() function and using the comedi_board() helper
to get the pointer in pci1723_attach().
