Board code cannot call mdiobus_register_board_info() when phylib
or mdio_device is a loadable module:
arch/arm/plat-orion/common.o: In function `orion_ge00_switch_init':
:(.init.text+0x474): undefined reference to `mdiobus_register_board_info'
I had a number of ideas for how this could be solved, but after the MDIO
code got split out from PHYLIB it has gotten too hard, so I'm basically
giving up, and only call the mdiobus_register_board_info() function
if the MDIO layer is built-in to avoid the link error. This is similar
to how we handle PHY registration on other ARM platforms.
Fixes: 90eff9096c01 ("net: phy: Allow splitting MDIO bus/device support from PHYs")

Utilize the ability to pass board specific MDIO bus information towards a
particular MDIO device thus allowing us to provide the per-port switch layout
to the Marvell 88E6XXX switch driver.
Since we would end-up with conflicting registration paths, do not register the
"dsa" platform device anymore.
Note that the MDIO devices registered by code in net/dsa/dsa2.c does not
parse a dsa_platform_data, but directly take a dsa_chip_data (specific
to a single switch chip), so we update the different call sites to pass
this structure down to orion_ge00_switch_init().

One of the last users of NO_IRQ on ARM is the switch initialization
code on orion5x, which sometimes passes a GPIO based IRQ number.
However, the driver doesn't actually use this number, and according
to Andrew Lunn never will do it for non-DT based machines, so
we can simply drop the irq argument.
Simplifying it further, we can also drop the static platform_device
and instead call platform_device_register_data(), which in turn
lets us mark the platform_data structures as __initdata and slightly
reduce the memory consumption.

For most devices, we know in advance whether they have an
interrupt line or not, so we can avoid passing NO_IRQ and
instead split fill_resources() into two interfaces, with
only the new fill_resources_irq() function taking an irq
argument, which it then can use unconditionally.

Out of the four ethernet devices on mv78xx0, only the first one
has an error interrupt line, for the other ones we pass NO_IRQ
and then ignore the argument.
In order to get closer to complete remove of NO_IRQ, this simply
drops the unused function arguments.

The watchdog device node is created in plat-orion/common.c
but depends on the bridge address that is platform specific,
so as a preparation for orion multiplatform support, we
move it out of the common code into orion5x and dove.
At the moment, dove does not use the watchdog, so I'm marking
the function as __maybe_unused for the moment. The compiler
will be able to compile out the device definition this way,
and we can easily add it later.

This change makes it so that instead of passing and storing a mii_bus we
instead pass and store a host_dev. From there we can test to determine the
exact type of device, and can verify it is the correct device for our switch.
So for example it would be possible to pass a device pointer from a pci_dev
and instead of checking for a PHY ID we could check for a vendor and/or device
ID.

In order to support other SoC, it's required to distinguish
the 'control' timer register, from the 'rstout' register
that enables system reset on watchdog expiration.
To prevent a compatibility break, this commit adds a fallback
to a hardcoded RSTOUT address.

This patch converts the Marvell MV643XX ethernet driver to use the
Marvell Orion MDIO driver. As a result, PowerPC and ARM platforms
registering the Marvell MV643XX ethernet driver are also updated to
register a Marvell Orion MDIO driver. This driver voluntarily overlaps
with the Marvell Ethernet shared registers because it will use a subset
of this shared register (shared_base + 0x4 to shared_base + 0x84). The
Ethernet driver is also updated to look up for a PHY device using the
Orion MDIO bus driver.
For ARM and PowerPC we register a single instance of the "mvmdio" driver
in the system like it used to be done with the use of the "shared_smi"
platform_data cookie on ARM.
Note that it is safe to register the mvmdio driver only for the "ge00"
instance of the driver because this "ge00" interface is guaranteed to
always be explicitely registered by consumers of
arch/arm/plat-orion/common.c and other instances (ge01, ge10 and ge11)
were all pointing their shared_smi to ge00. For PowerPC the in-tree
Device Tree Source files mention only one MV643XX ethernet MAC instance
so the MDIO bus driver is registered only when id == 0.
