comedi: dt2817: Add sanity checks for I/O base address
The "dt2817" driver uses an admin-supplied configuration option
(`it->options[0]`) to configure the I/O port base address of a DT2817
board. It currently allows any base address to be configured but the
hardware only supports base addresses (configured by on-board jumpers)
in the range 0x200 to 0x3f8 on 8-byte boundaries.
Add a sanity check to ensure the device is not configured at an
unsupported base address.
