David Bauer 0ce0d687de ipq40xx: disable double-tagging for PSGMII devices
This commit disables the double tagging recently backported to 19.07.

Operating the switch on the S-Tag had the advantage of being able to
have separate VLANs for the same C-VID on LAN and WAN. However, this
broke the ability to configure C-TAG modifications on the switch. Also
performance took a significant toll.

Fixes: commit 8c191712558c ("ipq40xx: fix ethernet vlan double tagging")
