VREFBUF not working on STM32H743?

[FLiu.11]

The current STM32CubeMX package cannot generate proper code to initialize the VREFBUF in STM32H743 MCU.

Modifications to HAL_MspInit() in stm32h7xx_hal_msp.c can fix this:

1. Add "__HAL_RCC_VREF_CLK_ENABLE();" to user code section 0.
2. In user code section 1,
   1. Add  HAL_SYSCFG_VREFBUF_VoltageScalingConfig(0x00000020);   // For 1.8V Vref+. or
   2. Add HAL_SYSCFG_VREFBUF_VoltageScalingConfig(0x00000030);    //  For 1.5V Vref+. or ...

Hello,

This is already raised internally for working and fix in the coming release (ID 86401).
