counter: stm32-timer-cnt: Reset TIM_TISEL to its default value in probe

Browse source 
The driver assumes that the input selection register (TIM_TISEL) is at
its reset default value. Usually this is the case, but the bootloader
might have modified it.

This bases on a similar patch submitted by Olivier Moysan for pwm-stm32.
