Enabling uart2 node currently leads to a /dev/ttyS1 device, with ttyS0..4 always present, causing confusion on the user's part.
dtc cannot resolve an overlay's &uart2 reference for strings, only for phandles, so it would need to hardcode the full node path.
Avoid this and enforce reliable numbering by adding serialX aliases for:
UART1 - on Wifi/BT connector UART2 - on Pi-2 connector UART3 - on Euler connector UART4 - on Euler connector
