[ Upstream commit 4411464d6f8b5e5759637235a6f2b2a85c2be0f1 ]
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.
Example impact on /proc/timer_list:
-Clock Event Device: timer +Clock Event Device: timer@fcfec400
