comedi: pcl816: Add sanity checks for I/O base address
The "pcl816" driver uses an admin-supplied configuration option
(`it->options[0]`) to configure the I/O port base address of a PCL-816
or PCL-814B ISA board. It currently allows any base address to be
configured but the hardware devices only support base addresses
(configured by on-board DIP switches) from 0 to 0x3F0 on 16-byte
boundaries.
Add a sanity check to ensure the device is not configured at an
unsupported base address.
