board: stm32h474i_disco: Small fixes on m4 core

Browse source 
ST-Link VPC is wired to UART_1.
Console should be assigned to this peripheral to be available.
By default UART_1 is assigned to m7 core and not available to m4.

This commit does not change this, but makes it easier to change
UART_1 assignment from m7 to m4 core.
