[FRAMGeneric] create Generic FRAM Object

[CasperBroekhuizen]

MB85RS is referenced a couple of times, in order to decouple from hardware, consider creating a generic FRAM.

Note that MB85RS driver is currently NOT compatible with CY15B104QN. (DelfiSpace/MB85RS#2).
Having a generic with two drivers will fix this issue as well.

As mentioned in DelfiSpace/MB85RS#2, I disagree and would keep the MB85RS protocol but make it generic for bigger memories as well (as the command set is compatible).

I am not so much in favor of auto-detecting the available device but more of creating a list of supported devices and forcing the user to choose. The autodetect scares me in case we have partial failures in orbit and we might start interpreting the data in a weird way.
