Madhavan Srinivasan 4d358e9e19 powerpc/sysfs: Disable writing to PURR in guest mode ...

commit d1211af304 upstream.

arch/powerpc/kernel/sysfs.c exports PURR with write permission.
This may be valid for kernel in phyp mode. But writing to
the file in guest mode causes crash due to a priviledge violation
