perf_counters: Fix bug in address encoding

The performance counters were accessible in user mode although
`mcounteren` or `scounteren` are not implemented. This commit moves the
writeable performance counters to machine mode. Access from
user/supervisor-space will trap as this is not implemented in Ariane.
