This series add low power timer as boadcast clockevent device.
Low power timer could runs even when CPUs are in idle mode and 
could wakeup them.

version 3:
- fix timer set sequence
- don't forget to free irq on remove function
- use devm_kzalloc to simplify errors handling in probe function

version 2:
- stm32 clkevent driver is now a child of the stm32 lp timer node
- add a probe function and adpat the driver to use regmap provide
  by it parent
- stop using timer_of helpers
- document the bindings inside stm32 lptimer yaml
