The PCI chip used on this board is from PLX Technologies Inc. As stated
in the comments of this driver, Dynalog does not have a registered PCI
vendor id so this board uses the PLX vendor id. The kernel provides an
id for that vendor in pci_ids.h (PCI_VENDOR_ID_PLX). Use it instead of
creating a duplicate with a different name.

Add preliminary support for the above PCIe boards. The interrupt
subdevice is not working yet as the boards need some additional
initialization to enable interrupts. Reserve an unused subdevice that
will eventually become a timer subdevice.
Some unused subdevices have been added between the used subdevices on
the PCIe215 and PCIe236. This is so the subdevice numbers will match a
pattern-matching feature to be added at a later date, where the
pattern-match specifications for a subdevice include pattern-match
results from other subdevices, specified by index.

The boards currently supported by this module all use port I/O. Support
memory-mapped I/O as well for future PCI/PCIe cards.
Define `struct dio200_region` to hold the type of register access and
either the port I/O base address or an ioremapped MMIO address. Add a
member `io` to the comedi device private data (`struct dio200_private`)
to hold this. Use this instead of `dev->iobase`. Memory-mapped
registers are mapped in `dio200_pci_attach()` and unmapped in
`dio200_detach()`.
`dio200_detach()` now uses the private data pointer `devpriv` set to
`dev->private` but can return early if it is `NULL` because no clean-up
needs to be done in that case.
