comedi: amplc_dio200_pci: Conditionally remove devices that use port I/O

In a future patch, the port I/O functions (`inb()`, `outb()`, and
friends will only be declared in the `HAS_IOPORT` configuration option
is enabled.

The amplc_dio200_pci module supports various Amplicon PCI and PCI
Express devices.  Some of the supported devices (the PCI ones) use port
I/O, and some of them (the PCIe ones) only use memory-mapped I/O.

Conditionally compile in support for the devices that need port I/O if
and only if the `CONFIG_HAS_IOPORT` macro is defined.

Add a run-time check in `dio200_pci_auto_attach()` to return an error if
the device actually requires port I/O (based on the PCI BAR resource
flags) but the `HAS_IOPORT` configuration option is not enabled.
