Subject: [PATCH] powerpc: remove dead module_find_bug code.


Doing some various "make randconfig" and came across an error when CONFIG_BUG
was not set. Looking further in this, I found that module_find_bug, defined
in powerpc arch code, is not called anywhere.

There is a static module_find_bug in lib/bug.c but that is a separate issue.
