Both clock nodes in the current device tree are named "clock" and hence end up being the same node. Rename the nodes to different names to avoid this. In fact, fixed-clock uses the node name as the clock name, so name the nodes after the clock they represent. Move the clocks into a "clocks" sub-node to group them and avoid any possible naming conflicts with other nodes also named after the device type. Signed-off-by: Stephen Warren <swarren@wwwdotorg.org>

* Each bank has a GPIO interrupt for itself.

* There is an overall "any bank" interrupt.

* In order, these are GIC interrupts 17, 18, 19, 20.
