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

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@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.
