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

The "ni_atmio" driver uses an admin-supplied configuration option
(`it->options[0]`) to configure the I/O port base address of an AT E
Series board.  Or, if the option value is zero, it can search ISA PNP
devices to look for a compatible board.  If the base address is
configured manually, it currently allows any base address to be
configured but the hardware only supports base addresses (configured by
a configuration utility and stored in nonvolatile memory) in the range
0x20 to 0xFFE0 on 32-byte boundaries.

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