The node(s) for the arch timer should not be in the cpus/cpu@N nodes.
Instead, there should be one node (in the root of the tree).
If this works currently it's only because the driver picks up one of the nodes,
and luckily it's the same as the others. This is not guaranteed to work in
future, and will likely break.

Also, this interrupts list is updated differently to all the other nodes. Typo?

Please fix this up to only have one timer node, in the root of the tree.
Thanks,
