comedi: dt2811: Add sanity checks for I/O base address
The "dt2811" driver uses an admin-supplied configuration option
(`it->options[0]`) to configure the I/O port base address of a supported
board in the DT2811 family. 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.
