module: allow restricted set of PID/CID registers to be examined

Peripherals could implement a smaller set of PID/CID registers for its
identification and reading unimplemented registers could cause aborts.
So allow modules to specify a valid set of PID/CID register values
that have to be examined against a set of expected values.
