[PATCH v2 1/5] kvm/powerpc: Export exit reasons as uapi

[Hemant Kumar]

To analyze the kvm exits with perf, we will need to map the exit codes
with the exit reasons. Such a mapping exists today in
trace_book3s.h. But its not exported to tools like perf.

This patch moves these kvm exit reasons and their mapping from
"arch/powerpc/kvm/trace_book3s.h" to
"arch/powerpc/include/uapi/asm/trace_book3s.h".

We will also need to change the path of "trace_book3s.h" included in files
"trace_hv.h" and "trace_pr.h".
