Review Comment:
I removed the 'STM32H7_PWR_DEFAULT_SUPPLY' macro in Kconfig.
I tried setting the 'STM32H7_HAVE_SMPS' macro in Kconfig to other chips.
- The "STM32 H7 Power Supply Selection" menu does not appear for STM32H7x3xx
- The "STM32 H7 Power Supply Selection" menu appears for STM32H7x5xx or
STM32H7x7xx
