I definitely want to test these on my SolidRun boards before these get
merged: the AR8035 on there is configured via pin-straps, and then
further tweaked with PHY quirks. Resetting with the iMX6 in the
wrong state may result in the AR8035 being reconfigured (even jumping
to a different MDIO address) and certainly would need the PHY quirks
re-running.
