BCM63268 need special configuration for their RGMII ports, so we need to be
able to identify them as a special BCM63xx switch.
In the meantime, let's add some missing BCM63xx SoCs to B53 MMAP device table.
This should be applied after "net: dsa: b53: add support for BCM63xx RGMIIs":

It works for those devices which only use ports 0-3 (Comtrend VR-3032u for example).

But it does seem to follow other examples in drivers/net/dsa/ FWIIW, I might have used of_device_is_compatible() without .data. Or only provided data for the exception case(s) and used something like this.

The comment I have says that the override bit ensures that what is populated in bits 5:4 which is the actual RGMII interface mode is applied. That mode can be one of: 0b00: RGMII mode 0b01: MII mode 0b10: RVMII mode 0b11: GMII mode even though this is not documented as such, I suspect that the override bit does not only set the mode, but also ensures that the delays are also applied.
