clocksource/drivers/stm32: Use the node name as timer name

As there are different timers on the stm32, use the node name for the timer
name in order to give the indication of which timer the kernel is using.

/proc/timer_list gives all the information with the right name, otherwise
we end up digging in the kernel log and /proc/interrupt to do the connection
between the used timer.
