The other issue is that the reverse is also true - platforms can be a
common baseboard, and its the CPU tile which changes.  That's standard
for the ARM development boards.

While the CPU tiles for platforms before Versatile Express had very
little variance other than the actual CPU, Versatile Express can have
dramatically different physical address maps depending on the CPU tile
fitted.  The only real common thing is the offsets for peripherals
within each chip select region.

As also said, all this should be solved by DT, so I don't see there's
much point in creating this abstraction just to have it obsoleted
shortly thereafter.  Much better to put that effort into ensuring that
DT can handle these setups...
