mem: Add a parameter which will make a memory truly a ROM.
This piggy-backs on the writeOK method which already exists. It also
modifies the flags returned as part of the memory's backdoor
descriptor which doesn't enforce that the memory is read only, but will
let the other party know it's expected not to write to it.
