clocksource/drivers/timer-of: Use unique device name instead of timer

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
