Christophe Leroy 9e00743aba powerpc/trace: Restrict hash_fault trace event to HASH MMU
'perf list' on powerpc 8xx shows an event named "1:hash_fault".

This event is pointless because trace_hash_fault() is called only
from mm/book3s64/hash_utils.c

Only define it when CONFIG_PPC_64S_HASH_MMU is selected.
