[PATCH V2 RFC 2/2] ARM: dts: BCM5301X: change Luxul XWR-3150 CPU port from 5 do 8

It is a bit fuzzy, but the hardware of port 8 is better designed for
the function of being the CPU port. We are expressing this hardware
property via actually using it as the CPU port.

Is this the only device in mainline which is affected?
