stm32h7: Reset USART clock selection (#23498)
This resets the USARTs' clock source selection to the default, in case
it has been changed by the bootloader.

This is required if booting from the ArduPilot bootloader which happens
to reset the clock selection to PLL.

Without this fix, UARTs (including the console) is garbled, so
presumably at an invalid baudrate.
