gianfar: some assorted cleanup

This is a cleanup series for the gianfar Ethernet driver, following up a
discussion in [1]. It is intended to precede a conversion of gianfar from
PHYLIB to PHYLINK API, which will be submitted later in its version 2.
However, it won't make a conversion cleaner, except for the last patch in
this series. Obviously this series is not intended for -stable.

The first patch looks super controversial to me, as it moves lots of code
around for the sole purpose of getting rid of static forward declarations
in two translation units. On the other hand, this change is purely
mechanical and cannot do any harm other than cluttering git blame output.
I can prepare an alternative patch for only swapping adjacent functions
around, if necessary.

The second patch is a trivial follow-up to the first one, making functions
that are only called from the same translation unit static.

The third patch removes some now unused macro and structure definitions
from gianfar.h, slipped away from various cleanups in the past.

The fourth patch, also suggested in [1], makes the driver consistently use
PHY connection type value obtained from a Device Tree node, instead of
ignoring it and using the one auto-detected by MAC, when connecting to PHY.
Obviously a value has to be specified correctly in DT source, or omitted
altogether, in which case the driver will fall back to auto-detection. When
querying a DT node, the driver will also take both applicable properties
into account by making a proper API call instead of open-coding the lookup
half-way correctly.

Historically, gianfar only used phy-connection-type DT property when
connected to PHY in the rgmii-id mode. It ignored the property otherwise,
relying on the connection type auto-detection carried out by MAC and
providing that reconstructed mode to of_phy_connect(). It also did not
consider alternative phy-mode property at all.

Make the driver properly query DT node for PHY connection type first and
use an obtained value if it was specified there. Otherwise, if a particular
DT relies on connection type auto-detection, fall back to reconstructing
the value from MAC registers, as before.

pull-request: can-next 2019-09-04 j1939

this is a pull request for net-next/master consisting of 21 patches.

the first 12 patches are by me and target the CAN core infrastructure.
They clean up the names of variables , structs and struct members,
convert can_rx_register() to use max() instead of open coding it and
remove unneeded code from the can_pernet_exit() callback.

The next three patches are also by me and they introduce and make use of
the CAN midlayer private structure. It is used to hold protocol specific
per device data structures.

The next patch is by Oleksij Rempel, switches the
&net->can.rcvlists_lock from a spin_lock() to a spin_lock_bh(), so that
it can be used from NAPI (soft IRQ) context.

The next 4 patches are by Kurt Van Dijck, he first updates his email
address via mailmap and then extends sockaddr_can to include j1939
members.

The final patch is the collective effort of many entities (The j1939
authors: Oliver Hartkopp, Bastian Stender, Elenita Hinds, kbuild test
robot, Kurt Van Dijck, Maxime Jayat, Robin van der Gracht, Oleksij
Rempel, Marc Kleine-Budde). It adds support of SAE J1939 protocol to the
CAN networking stack.

SAE J1939 is the vehicle bus recommended practice used for communication
and diagnostics among vehicle components. Originating in the car and
heavy-duty truck industry in the United States, it is now widely used in
other parts of the world.
