Add support for the CN9130 SOM attached to a Clearfog Base platform.
This is similar to the Armada 388 based Clearfog Base platform.

Add the dts include file for the SolidRun CN9130 SOM (which is designed
to be attached to another board to make a functional system.) This SOM
is designed to be inter-changeable with the Armada 388 SOM used on
SolidRun's Clearfog Base and Pro platforms.

Use phy_query_inband() with the initial mode when configuring copper
SFP modules to determine whether we should use inband or PHY mode. This
allows us to remove the BCM84881 specific detection from phylink, and
instead rely on the PHY driver giving us this detail.
We can use a simple check here - if the PHY reports that the inband
information is valid, but sets no other bits, then inband is definitely
not supported.

Since the BCM84881 driver always provides phy->supported_interfaces,
and the driver is required for this PHY, move phylink_phy_no_inband()
to the case where this is non-empty.

Move the SFP autoneg mode into struct phylink rather than passing it
into phylink_sfp_config(). This is generally MLO_AN_INBAND except when
we have a copper SFP with a Broadcom 84881 PHY.

The modalias string provided in the uevent sysfs file does not conform
to the format used in PHY driver modules. One of the reasons is that
udev loading of PHY driver modules has not been an expected use case.
This patch changes the MODALIAS entry for only PHY devices from:
MODALIAS=of:Nethernet-phyT(null)
to:
MODALIAS=mdio:00000000001000100001010100010011
Other MDIO devices (such as DSA) remain as before.
However, having udev automatically load the module has the advantage
of making use of existing functionality to have the module loaded
before the device is bound to the driver, thus taking advantage of
multithreaded boot systems, potentially decreasing the boot time.
However, this patch will not solve any issues with the driver module
not being loaded prior to the network device needing to use the PHY.
This is something that is completely out of control of any patch to
change the uevent mechanism.

phy_error() is called from phy_interrupt() or phy_state_machine(), and
uses WARN_ON() to print a backtrace. The backtrace is not useful when
reporting a PHY error.
However, a system may contain multiple ethernet PHYs, and phy_error()
gives no clue which one caused the problem.
Replace WARN_ON() with a call to phydev_err() so that we can see which
PHY had an error, and also inform the user that we are halting the PHY.

Provide phy driver start/stop hooks so that the PHY driver knows when

firmware is not present, and also so that we can sanely support SFPs
behind the PHY.

Configure the Macchiatobin 10G PHY LED modes to correct their polarity.
We keep the existing LED behaviours, but switch their polarity to
reflect how they are connected. Tweak the LED modes as well to be:
left: off = no link
solid green = RJ45 link up (not SFP+ cage)
flash green = traffic
right: off = no link
solid green = 10G
solid yellow = 1G
flash green = 100M
flash yellow = 10M

Add support for configuring the LEDs. Macchiatobin has an oddity in
that the left LED goes out when the cable is connected, and flashes
when there's link activity. This is because the reset default for
the LED outputs assume that the LED is connected to supply, not to
ground. Add support for configuring the LED modes and polarities.
