clocksource/drivers/stm32: Add oneshot mode
The stm32 timer block is able to have a counter and a comparator.
Instead of using the auto-reload register for periodic events, we switch to oneshot mode by using the comparator register.
The timer is able to generate an interrupt when the counter overflows but we don't want that as this counter will be use as a clocksource in the next patches. So it is disabled by the UDIS bit of the control register.

clocksource/drivers/stm32: Compute a prescaler value with a targeted rate
The prescaler value is arbitrarily set to 1024 without any regard to the timer frequency. For 32-bit timers, there is no need to set a prescaler value as they wrap in an acceptable interval and give the opportunity to have precise timers on this platform. However, for 16-bit timers a prescaler value is needed if we don't want to wrap too often per second which is inefficient and adds more and more error margin. With a targeted clock of 10MHz, the 16 bits are precise enough whatever the timer frequency is as we will compute the prescaler.

clocksource/drivers/stm32: Fix kernel panic with multiple timers
The current code hides a couple of bugs:
- The global variable 'clock_event_ddata' is overwritten each time the init function is invoked.
This is fixed with a kmemdup() instead of assigning the global variable. That prevents a memory corruption when several timers are defined in the DT.
- The clockevent's event_handler is NULL if the time framework does not select the clockevent when registering it, this is fine but the init code generates in any case an interrupt leading to dereference this NULL pointer.
The stm32 timer works with shadow registers, a mechanism to cache the registers. When a change is done in one buffered register, we need to artificially generate an event to force the timer to copy the content of the register to the shadowed register.
The auto-reload register (ARR) is one of the shadowed register as well as the prescaler register (PSC), so in order to force the copy, we issue an event which in turn leads to an interrupt and the NULL dereference.
This is fixed by inverting two lines where we clear the status register before enabling the update event interrupt.
As this kernel crash is resulting from the combination of these two bugs, the fixes are grouped into a single patch.

clocksource/drivers: Rename CLOCKSOURCE_OF_DECLARE to TIMER_OF_DECLARE
The CLOCKSOURCE_OF_DECLARE macro is used widely for the timers to declare the clocksource at early stage. However, this macro is also used to initialize the clockevent if any, or the clockevent only.
It was originally suggested to declare another macro to initialize a clockevent, so in order to separate the two entities even they belong to the same IP. This was not accepted because of the impact on the DT where splitting a clocksource/clockevent definition does not make sense as it is a Linux concept not a hardware description.
On the other side, the clocksource has not interrupt declared while the clockevent has, so it is easy from the driver to know if the description is for a clockevent or a clocksource, IOW it could be implemented at the driver level.
So instead of dealing with a named clocksource macro, let's use a more generic one: TIMER_OF_DECLARE.
The patch has not functional changes.

clocksource/drivers/stm32: Convert init function to return error
The init functions do not return any error. They behave as the following:
- panic, thus leading to a kernel crash while another timer may work and make the system boot up correctly
or
- print an error and let the caller unaware if the state of the system
Change that by converting the init functions to return an error conforming to the CLOCKSOURCE_OF_RET prototype.
Proper error handling (rollback, errno value) will be changed later case by case, thus this change just return back an error or success in the init function.

clockevents/drivers/stm32: Migrate to new 'set-state' interface
Migrate stm32 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.
