Merge branch 'dsa-platform-remove-void'

Uwe Kleine-König says:

====================
net: dsa: Convert to platform remove callback returning void

this series converts all platform drivers below drivers/net/dsa to use
remove_new. The motivation is to get rid of an integer return code
that is (mostly) ignored by the platform driver core and error prone on
the driver side.

See commit 5c5a7680 ("platform: Provide a remove callback that
returns no value") for an extended explanation and the eventual goal.

There are no interdependencies between the patches. As there are still
quite a few drivers to convert, I'm happy about every patch that makes
it in. So even if there is a merge conflict with one patch until you
apply or a subject prefix is suboptimal, please apply the remainder of
this series anyhow.
