Michael Ellerman af3fdce4ab Revert "powerpc/code-patching: Improve verification of patchability" 
This reverts commit 8b8a8f0ab3f5519e45c526f826a655817486c5bb.

As reported[1] by Sachin this causes problems with ftrace, and it also
causes the code patching selftests to fail as reported[2] by Stephen.

So revert it for now.
