arm64: dts: renesas: r8a779f0: Disable rswitch ports by default

The Renesas Ethernet Switch has three independent ports.  Each port can
act as a separate interface, and can be enabled or disabled
independently.  Currently all ports are enabled by default, hence board
DTS files that enable the switch must disable all unused ports
explicitly.

Disable all ports by default, and explicitly enable ports that are used,
next to their configuration.
