Merge branch 'net-dsa-lantiq-a-bunch-of-fixes'

Daniel Golle says:

====================
net: dsa: lantiq: a bunch of fixes

This series is the continuation and result of comments received for a fix
for the SGMII restart-an bit not actually being self-clearing, which was
reported by by Rasmus Villemoes.

A closer investigation and testing the .remove and the .shutdown paths
of the mxl-gsw1xx.c and lantiq_gswip.c drivers has revealed a couple of
existing problems, which are also addressed in this series.
