Add a backport patch and pending patches needed by upcoming PSE drivers
which are built as modules and probed after the MAC/PHY.
The net effect for module-built PSE controllers: attachment to PHYs
happens via the lifecycle notifier rather than via probe-time
-EPROBE_DEFER coupling, so the MDIO/DSA probe no longer sees any
PSE-originated -EPROBE_DEFER and the probe-retry storm is gone.
