CubeMX generate "ilegal" initialisation code for TIM6 in LL API

[Michal Dudka]

CubeMX TIM6 initialisation code for LL API ("MX_TIM6_Init") calls function

LL_TIM_DisableMasterSlaveMode(TIM6) set bit in "reserved" memory location. TIM6 do not contain MasterSlave controller.

Tested on CubeMX 5.6.1 with H743ZI (Nucleo).

Correction - it clears bit in reserved location...
