[PATCH 09/20] clocksource/drivers/timer-of: Store the device node pointer

[Daniel Lezcano]

Under certain circumstances, some specific operations must be done with the
device node pointer, that forces the timer code to propagate the pointer to
the functions which need it. In order to consolidate the function signatures
in the different drivers by using the timer-of structure, let's store it in
the timer-of structure as a handy pointer when it is needed.
