net: mdio: setup both fwnode and of_node

The first patch in this series fixes a bug introduced by mistake in the
previous ACPI MDIO patch set.

The next two patches are adding a new helper which takes a device and a
fwnode_handle and populates both the of_node and fwnode so that we make
sure that a bug like this does not happen anymore.
Also, the new helper is used in the MDIO area.

By mistake, the of_node of the MDIO device was not setup in the patch
linked below. As a consequence, any PHY driver that depends on the
of_node in its probe callback was not be able to successfully finish its
probe on a PHY, thus the Generic PHY driver was used instead.

Fix this by actually setting up the of_node.

net: gianfar: 64-bit statistics and rx_missed_errors counter

This series replaces the legacy 32-bit statistics to proper 64-bit ditto,
and implements rx_missed_errors counter on top of that.

The device supports a 16-bit RDRP counter, and a related carry bit and
interrupt, which allows implementation of a robust 64-bit counter.
====================

Signed-off-by: David S. Miller <davem@davemloft.net>

Devices with RMON support has a 16-bit RDRP counter.  It provides: "Receive
dropped packets counter. Increments for frames received which are streamed
to system but are later dropped due to lack of system resources."

To handle more than 2^16 dropped packets, a carry bit in CAR1 register is
set on overflow, so we enable irq when this is set, extending the counter
to 2^64 for handling situations where lots of packets are missed (e.g.
during heavy network storms).

The memset on CAMx is wrong, as it actually unmasks all carry irq's,
which we clearly are not interested in.

The memset on CARx registers is just pointless, as they are W1C.

So let's just stop the memset before CAR1.
