[U-Boot-Users] [85xx][UPDATE][PATCH] Update MPC8544DS to use libfdt

[Kumar Gala]

Updated the MPC8544DS config to use libfdt and assume use of aliases for
ethernet, pci, and serial for the various fixups that are done.

Signed-off-by: Kumar Gala <galak at kernel.crashing.org>
---

Based on my libfdt_testing branch.  Updated to use bi_intfreq when setting
clock-freq on the cpu node and to set CONFIG_OF_STDOUT_VIA_ALIAS.
