mem: Add a class to describe a back door request.
In cases where a back door is not being requested alongside a packet
or request, there needs to be a structure which describes the address
range to use, and what type of access the back door should support. It
would be possible to make a Packet/Request to carry that information,
but those types are actually pretty big, and have a lot of extra
overhead which would be overkill for this purpose.
