Migrate vt8500 driver to the new 'set-state' interface provided by
clockevents core, the earlier 'set-mode' interface is marked obsolete
now.
This also enables us to implement callbacks for new states of clockevent
devices, for example: ONESHOT_STOPPED.

Instead of letting each driver call of_node_put do it centrally in the
loop that also calls the CLOCKSOURCE_OF_DECLARE callbacks. This is less
prone to error and also moves getting and putting the references into the
same function.
Consequently all respective of_node_put calls in drivers are removed.

This ensures that a function pointer passed into CLOCKSOURCE_OF_DECLARE
takes the same arguments that we use for calling that function later.
Also fix the extraneous semicolon at end of the CLOCKSOURCE_OF_DECLARE
definition.

In cases where we have multiple nodes of the same type, we may need the
node pointer to know which node was matched. Passing the node pointer
also keeps the init function from having to match the node a 2nd time.
Update bcm2835, vt8500, and tegra20 init functions for the new function
prototype. Further tegra20 clean-ups are in follow-up commit.

This patch converts arch-vt8500 to make use of CLKSRC_OF. Doing so
removes the need for include/linux/vt8500_timer.h as vt8500_timer_init
no longer needs to be visible outside vt8500_timer.c
