comedi: pcmad: Add sanity checks for I/O base address
The "pcmad" driver uses an admin-supplied configuration option
(`it->options[0]`) to configure the I/O port base address of a
PCM-A/D-12 or PCM-A/D-16 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 0 to 0x3FC on 4-byte boundaries.
Add a sanity check to ensure the device is not configured at an
unsupported base address.
