Subject: s390/qeth: shift some bridgeport code around
Git-commit: 8ca769e2b88f9e564aecdfab54fcc5a9d20190c1
Patch-mainline: v5.6-rc1
References: jsc#SLE-13690

qeth_l2_setup_bridgeport_attrs() is entirely unrelated to sysfs
functionality, move it where it belongs.
While at it merge all the bridgeport-specific code in the set-online
path together.
