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.
