On BPI-R2-Pro board this port is not connected and only Port 5 is connected to gmac of SoC. Replace this hardcoded CPU-Port with a member in mt7530_priv struct which is set in mt753x_cpu_port_enable to the right port. I defined a default in probe (in case no CPU-Port will be setup) and if both cpu-port were setup port 6 will be used like the const prior this patch. In mt7531_setup first access is before we know which port should be used (mt753x_cpu_port_enable) so section "BPDU to CPU port" needs to be moved down.
