powerpc/cell: Only iterate over online nodes in cbe_init_pm_irq()
None of the cell platforms support CPU hotplug, so we should iterate
only over online nodes when setting PMU interrupts.
This also fixes a warning during boot when NODES_SHIFT is large enough:

This is caused by us overflowing our linear revmap because we're
requesting too many interrupts.
