comedi: pcmda12: Add sanity checks for I/O base address
The "pcmda12" driver uses an admin-supplied configuration option
(`it->options[0]`) to configure the I/O port base address of a
PCM-D/A-12 or PCM-A/D-16 board. It currently allows any base address to
be configured. I cannot find a full manual, but the short datasheet
says it uses 15 consecutive I/O addresses on "any even sixteen port
boundary", so assume it supports base addresses (configured by on-board
jumpers) in the range 0 to 0x3E0 on 32-byte boundaries.
Add a sanity check to ensure the device is not configured at an
unsupported base address.
