changes v6:
- take over this patch set
- rebase against latest netdev-next and fix regressions
- disable VLAN support for KSZ8863. KSZ8863's VLAN is not compatible to the
  KSZ8795's. So disable it for now and mainline it separately.

This series adds support for the ksz88x3 driver family to the dsa based
ksz drivers. The driver is making use of the already available ksz8795
driver and moves it to an generic driver for the ksz8 based chips which
have similar functions but an totaly different register layout.
