After some analysis with Florian (thnx) we found out that the current 
implementation is broken:

https://patchwork.ozlabs.org/patch/836538/
https://github.com/torvalds/linux/commit/c499696e7901bda18385ac723b7bd27c3a4af624#diff-a2b6f8d89e18de600e873ac3ac43fa1d

Florians comment:

c499696e7901bda18385ac723b7bd27c3a4af624 ("net: dsa: b53: Stop using
dev->cpu_port incorrectly") since it would result in no longer setting
the CPU port as tagged for a specific VLAN. Easiest way for you right
now is to just revert it, but this needs some more thoughts for a proper
upstream change. I will think about it some more.

Ciao,
Gerhard
