Merge branch 'lantiq-Minor-fixes-for-vrx200-and-gswip'

Hauke Mehrtens says:

====================
net: lantiq: Minor fixes for vrx200 and gswip

These are mostly minor fixes to problems addresses in the latests round
of the review of the original series adding these driver, which were not
applied before the patches got merged into net-next.
In addition it fixes a data bus error on poweroff.
