The board supported by this driver can generate an interrupt based
on the state of input channels 0-15.
The apci1032_intr_insn_config() function is used to configure which
inputs are used to generate the interrupt. Currently this function
is broken since it does not follow the comedi API for insn_config
functions. Fix this function by implementing the, currently unused,
config instruction INSN_CONFIG_DIGITAL_TRIG.
Add the remaining subdevice operations necessary for the interrupt
subdevice to support async commands.
Fix the subdevice initialization so that if the interrupt is not
available the subdevice is set as COMEDI_SUBD_UNUSED.

The addi-data drivers use send_sig() to let the user know when an
interrupt has occurred. The "standard" way to do this in the comedi
subsystem is to have a subdevice that supports asynchronous commands
and use comedi_event() to signal the user.
Remove the send_sig() usage in this driver. This also allows removing
the dev->private usage since tsk_Current was the only member still
being used in the private data.

Support auto-attachment of supported PCI devices by adding the
`auto_attach()` hook (`pci9118_auto_attach()`) to the `struct
comedi_driver`. This is called via `comedi_pci_auto_attach()` at PCI
probe time.
Previously, the driver's call to `comedi_pci_auto_config()` would fall
back to the old method of auto-attaching devices and would fail because
it couldn't find a board name matching the driver name. The new method
doesn't care about that.
There are still a few problems. All the boards supported by this driver
have the same PCI vendor and device ID, so it will just pick the first
supported board type, "pci9118dg". (Other supported board types have
different AI ranges or different AI speeds, but are otherwise the same.)
Also, manual attachment of devices allows several optional features to
be configured, such as use of an external multiplexord, specified
sample&hold delays and options to ignore certain hardware errors. These
will all be set to defaults for auto-attached devices. A future version
of the driver may address these issues via configurable device
attributes.
