This adds the ability to use USART2 as a console if wanting to use a console
without going through the ST-Link VCOM port. This required when using an
external debugger or trace with this board.
## Summary
The Nucleo H563ZI development board supports using an external debugger or
trace over the onboard MIPI20 connector (CN5) when a jumper is applied to JP1.
However, this removes RX from onboard ST-Link VCOM port. This change allows
configuring USART2 as the serial console to allow full serial console
connection when using an external debugger.
Also organized a couple of defines in `board.h` to align with their location
in other STM32 board files.
## Impact
Makes Nucleo H563ZI board support compatible with external debuggers while
maintaining serial console.
## Testing
- Host: Ubuntu 24.04 Docker container on Ubuntu 24.04 host (WSL2)
- Compiler: `arm-none-eabi-gcc (Arm GNU Toolchain 13.3.Rel1 (Build
arm-13.24)) 13.3.1 20240614`
- Configuration: `nucleo-h563zi:nsh` with modifications:
- Enable `USART2` in peripheral selection
- Switch serial console to `USART2_SERIAL_CONSOLE`
NSH was confirmed to run over USART2.
This is the result of `make savedefconfig` including the tweaks to enable
USART2 console:
