The problem is that we don't know about 'any later chips' and we don't
know whether the MX5_ assumption stays true for later MX5 chips.

To end this, let's just use the complete names for all i.MX defines,
that is MX51 for MX51 and MX53 for MX53. It's the only way to handle
this consistently for *all* i.MX, not only the MX5 ones.

Uwe has worked a lot on making the overhead for this as little s
possible and in the end we are just talking about a handfull of base
addresses and interrupt/dma request numbers. It should be simple to add
them without asking the question 'is this mxx specific or mxy also?'
over and over again.
