powerpc/mce: Avoid using irq_work_queue() in realmode
In realmode mce handler we use irq_work_queue() to defer
the processing of mce events, irq_work_queue() can only
be called when translation is enabled because it touches
memory outside RMA, hence we enable translation before
calling irq_work_queue and disable on return, though it
is not safe to do in realmode.
To avoid this, program the decrementer and call the event
processing functions from timer handler.
