Thanks!

How about this patch that does 2 things:

1) Add separate 5475 and 5485 lists of control registers.  It seems wrong to 
accept control registers that don't exist :) Of course, we may have a backwards 
compatibility issue, should people have been using -mcpu=5475 to compiler for 
some random mcf4ve chip.  But then Freescale only list 5407, 5475 and 5485 
families :)  I didn't think it worthwhile using a common array for the 5475 and 
5485 families -- I find it much easier to just have a 1:1 correspondance between 
coldfire families and control register lists.

2) Adds the ColdFire documented names for the registers, together with the 
legacy names we've used so far.  This addresses the bug report I had, namely not 
accepting asid.

ok?
