commit e9c56f8d2f851fb6d6ce6794c0f5463b862a878e upstream.
The sun4i-emac driver uses devm_request_irq at .ndo_open time, but relies on
the managed device mechanism to actually free it. This causes an issue whenever
someone wants to restart the interface, the interrupt still being held, and not
yet released.
Fall back to using the regular request_irq at .ndo_open time, and introduce a
free_irq during .ndo_stop.

The EMAC driver can't work without its associated PHY driver. Reflect
this in the Kconfig options by selecting it.

All drivers that select MII also need to select NET_CORE because MII
depends on it. This is a bit ridiculous because NET_CORE is just a
menu option that doesn't enable any code by itself.
There is also no need for it to be a visible option, since its users
all select it.

Commit 0998d06310 (device-core: Ensure drvdata = NULL when no
driver is bound) removes the need to set driver data field to
NULL.

The newly added sun4i-emac driver causes a build error when
CONFIG_NET_POLL_CONTROLLER is set, because it attempts to
assign a pointer to netdev->poll_controller, which has
been replaced with ops->ndo_poll_controller in 2.6.31!
The correct assignment is present as well, so we just need
to remove the wrong one.

The Allwinner A10 has an ethernet controller that seem to be developped
internally by them.
The exact feature set of this controller is unknown, since there is no
public documentation for this IP, and this driver is mostly the one
published by Allwinner that has been heavily cleaned up.
