Merge branch 'phy_stop-synchronous'

====================
net: phy: make phy_stop() synchronous

There have been few not that successful attempts in the past to make
phy_stop() a synchronous call instead of just changing the state.
Patch 1 of this series addresses an issue which prevented this change.
At least for me it works fine now. Would appreciate if Geert could
re-test as well that suspend doesn't throw an error.
