[PATCH] [PowerPC] MPC8272ADS: fix device tree for 8 MB flash size

[Wolfgang Denk]

The current device tree for the MPC8272ADS assumes a mapping of 32 MB
of NOR flash at 0xFE00.0000, while there are actually only 8 MB on
the boards, mapped at 0xFF80.0000. When booting an uImage with such a
device tree, the kernel crashes because 0xFE00.0000 is not mapped.

Also introduce aliases for serial[01] and ethernet[01].

I am not really sure what the typical flash size on MPC8272ADS boards
is. The board I used for testing is marked as "Prototype", so it may
not be the release configuration. On the other hand, the manual also
says 8 MB, Vitaly Borduk confirms 8 MB on his board, too, and Scott
Wood eventually tested only with cuImage which fixes up the localbus
mappings, thus eventually concealing the issue.

I'm posting this as reference in case the 8 MB should turn out to be
correct. -- wd
