arm64: dts: renesas: r8a779f0: Add labels for rswitch ports

Introduce labels for each rswitch port in the form 'rswitch_portN'.
Those can be used to access rswitch port nodes directly, which is going
to be useful in reducing DT indentation slightly as well as in the DT
/aliases node to reference the rswitch ports as ethernetN interfaces.
No functional change.
