Subject: [PATCH] fix: Eliminated HardFault after reset under debug

Reported in https://github.com/STMicroelectronics/x-cube-azrtos-h7/issues/38
PCC/MXCubeGenerated/Core/Src/stm32h7xx_hal_timebase_tim.c
- Moved interrupt enable after timer initialization. After reset, timer interrupt was firing before the handle was initialized, resulting in a HardFault.
