comedi: amplc_dio200: Add sanity checks for I/O base address
The "amplc_dio200" driver uses an admin-supplied configuration option
(`it->options[0]`) to configure the I/O port base address of a supported
board (PC212E, PC214E, PC215E, PC218E, or PC272E). It currently allows
any base address to be configured but the hardware only supports base
addresses (set by on-board DIP switches) in the range 0 to 0xFE0 on
32-byte boundaries. (Technically, the DIP switches allow 16-byte
boundaries, but I do not think that is advisable given that the boards
decode a 32-byte address range.)
Add a sanity check to ensure the device is not configured at an
unsupported base address.
