The STM32H725/735 HAL function IS_TIM_MASTER_INSTANCE() is missing a check for TIM12, which is a valid master (has MMS bits in CR2).

[Andrew Sterian]

For example, here is the function definition for the STM32H725:

/****** TIM Instances : master mode available (TIMx_CR2.MMS available )********/

#define IS_TIM_MASTER_INSTANCE(INSTANCE) (((INSTANCE) == TIM1) || \

                      ((INSTANCE) == TIM2) || \

                      ((INSTANCE) == TIM3) || \

                      ((INSTANCE) == TIM4) || \

                      ((INSTANCE) == TIM5) || \

                      ((INSTANCE) == TIM6) || \

                      ((INSTANCE) == TIM7) || \

                      ((INSTANCE) == TIM8) || \

                      ((INSTANCE) == TIM15) || \

                      ((INSTANCE) == TIM23) || \

                      ((INSTANCE) == TIM24))

Note that TIM12 is missing.

Other MCU's may be affected but I'm only looking at the 725/735 for now.
