[POWERPC] 83xx: Clean up / convert mpc83xx board DTS files to v1 format.

[POWERPC] 83xx: Clean up / convert mpc83xx board DTS files to v1 format.

This patch converts the remaining 83xx boards to the dts-v1 format.
This includes the mpc8313_rdb, mpc832x_mds, mpc8323_rdb, mpc8349emitx,
mpc8349emitxgp and the mpc836x_mds.

The mpc8315_rdb mpc834x_mds, mpc837[789]_*, and sbc8349 were already
dts-v1 and only undergo minor changes for the sake of formatting
consistency across the whole group of boards; i.e.  the idea being
that you can do a "diff -u board_A.dts board_B.dts" and see something
meaningful.

The general rule I've applied is that entries for values normally
parsed by humans are left in decimal (i.e. IRQ, cache size, clock
rates, basic counts and indexes) and all other data (i.e. reg and
ranges, IRQ flags etc.) remain in hex.

I've used dtc to confirm that the output prior to this changeset
matches the output after this changeset is applied for all boards.
