[PATCH] ppc: eliminate gcc warning in prom.c

[Paul Mackerras <paulus@samba.org>]

This patch shuts up a couple of gcc "variable may be used
uninitialized" warnings.  The warnings are invalid - the code is such
that the variables are in fact initialized before being used - but gcc
isn't smart enough to see that.  This patch eliminates the warnings.
