Also, here is the same refactoring done on the
mpc8572ds.dts file too.
And, perhaps more important than doing this work
on this one file, it shows that the first section
of both this 8572 DTS file and the 8641 DTS file
are almost identical throughout the /define/ section.
Minor refactoring needed in the 8641 variant.
The only "real" difference is 8641 says "TSEC" and
the 8572 says "eTSEC", and one weird interrupt thing
in the serial node. Dunno.
Enjoy,
jdl
