ARM: debug: stm32: add UART early console configuration for STM32F7

Browse Source 
Early console is hardcoded on USART1 in current implementation.
With this patch, default UART instance is USART1, but other UART instances
can be configured by setting physical and virtual base addresses in
menuconfig.

Say Y here if you want kernel low-level debugging support
on STM32F7 based platforms, which default UART is wired on
USART1.
USART1, but another UART instance can be selected by modifying
CONFIG_DEBUG_UART_PHYS.
If unsure, say N.
