Flex bus definition update for Coldfire 5253.
originally work by Jate Sujjavanich <jsujjavanich@syntech-fuelmaster.com>
----
The defines in arch/m68k/include/coldfire/flexbus.h are not compatible with
the 5235 processor. The registers in struct fbcs are different sizes from
those in the 5235. Also, the defines are a little different.
This is what I have so far. Comments?
