Bug in STM32 LL timer library

[SPeir]

I'm seeing a bug in STM32Cube_FW_F1_V1.6.0.

I was using timer 2 in up counting mode with a prescale value of 6399, however the prescale value was not being used. After stepping through the code I noticed a bug in the LL_TIM functions.

The LL_TIM_DisableUpdateEvent function is supposed to SET bit UDIS in the CR1 register to disable UEV. Likewise, the LL_TIM_EnableUpdateEvent function is supposed to CLEAR bit UDIS in the CR1 register to enable UEV.

This is swapped in version 1.6.0. I tried using LL_TIM_DisableUpdateEvent instead of Enable and now it works.
