Board names for 4xx

[David Gibson]

The patch below allows publishing the type of board the kernel is
running on in /proc/cpuinfo (under "machine") for 4xx machines.  It
displays Walnut boards as "IBM Walnut" and (currently) all others
simply as "4xx".  Adding other boards is trivial - just a #define in
the relevant header file.  It also eliminates a warning in
ppc4xx_setup.c
