[PATCH] power: Remove arch specific module bug stuff

[PATCH] power: Remove arch specific module bug stuff

[linux]

From: "Dr. David Alan Gilbert" <linux@treblig.org>

The last function to reference module_bug_list went in 2008's
  commit b9754568ef17 ("powerpc: Remove dead module_find_bug code")
but I don't think that was called since 2006's
  commit 73c9ceab40b1 ("[POWERPC] Generic BUG for powerpc")

Now that the list has gone, I think we can also clean up the bug
entries in mod_arch_specific.

Lightly boot tested.
