version 4:
- split patch in 3 parts
  - convert code to timer_of
  - only use 32 bits timers
  - add clocksource support
Hello Daniel,

Does the patches split sound good for you ?

Regards,
Benjamin
version 3:
- fix comments done by Daniel
- use timer_of helper functions

version 2:
- fix uninitialized variable

These patches implements clocksource and clockevent by using only one hardware block.
Getting both clock source and events on the same hardware lead to change quite
a lot driver code.
It also limits usage of clocksource to 32 bits timers because 16 bits ones
aren't enough accurate.
Thanks to timer_fo helpers this series includes minor clean up in structures,
function prototypes and driver name.

Since 16 bits timers become useless it also removes them from stm32f4 and
stm32f7 devicetree.
