comedi: ni_atmio16d: Add sanity checks for I/O base address

The "ni_atmio16d" driver uses an admin-supplied configuration option
(`it->options[0]`) to configure the I/O port base address of an
AT-MIO-16 o AT-MIO-16D board.  It currently allows any base address to
be configured but the hardware only supports base addresses (configured
by on-board DIP switches) in the range 0 to 0x3E0 on 32-byte boundaries.

Add a sanity check to ensure the device is not configured at an
unsupported base address.
