One less device_node.name pointer use to get rid of. I want to drop it from the struct and stop storing both node name strings. Reviewed-by: Rob Herring <robh@kernel.org> Rob

If a hardware-specific driver does not provide a name, the timer-of core falls back to device_node.name. Due to generic DT node naming policies, that name is almost always "timer", and thus doesn't identify the actual timer used. Fix this by using device_node.full_name instead, which includes the unit addrees.
