comedi: pcl812: Add sanity checks for I/O base address
The "pcl812" driver uses an admin-supplied configuration option
(`it->options[0]`) to configure the I/O port base address of various
analog/digital I/O ISA boards from Advantech, ADLINK, and ICP DAS. 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 or 0x200 (depending on the model) to 0x3F0 on 16-byte
boundaries.
Store the minimum supported I/O base addresses in the static board
information array elements and add a sanity check to ensure the device
is not configured at an unsupported base address.
