Scott Wood 28c5bcf74f KVM: PPC: Move and undef TRACE_INCLUDE_PATH/FILE 
TRACE_INCLUDE_PATH and TRACE_INCLUDE_FILE are used by
<trace/define_trace.h>, so like that #include, they should
be outside #ifdef protection.

They also need to be #undefed before defining, in case multiple trace
headers are included by the same C file.  This became the case on
book3e after commit cf4a608515 ("powerpc/mm: Add missing tracepoint for
tlbie"), leading to the following build error:

   CC      arch/powerpc/kvm/powerpc.o
In file included from arch/powerpc/kvm/powerpc.c:51:0:
arch/powerpc/kvm/trace.h:9:0: error: "TRACE_INCLUDE_PATH" redefined
