They're allocated using standard newbus API,
which means that we rely on miibus to handle the allocation.
Add VSC8504 to the list of supported PHYs, as it is similar enough
to the VSC8501 that is already supported by this driver.

DP83822 is a 10/100 Texas Instruments PHY.
Link status change interrupts are supported by the driver,
however not all boards have the PHY interrupt wired.
Because of that if failure to allocate an IRQ is not treated as an error.

DP83867 is a 10/100/1000 Texas Instruments PHY.
Only SGMII mode is supported.
Link status changes can be checked through an interrupt generated by the PHY,
if available

Create a new miibus OFW specific layer leveraging miibus_fdt.c code.
PHY drivers can than read the properties using device_get_property(9) API.
Resource(interrupt) allocation is also supported.
In order to enable this each NIC/switch driver will have to be modified,
because of how miibus is attached to the parent driver.

It is used to limit the max advertised speed.
The value is read from DT by mii_fdt code.

In some cases we might want to limit the max speed advertised below of what
the PHY is capable of.
This is usually the case when we connect 1G capable PHY to 100M MAC, or when
some exotic physical connection is used.
Add a new mii_maxspeed field to mii_softc and parse it in mii_phy_dev_attach.
Speed limit is normally located in DT.
The property is already parsed in mii_fdt.c, but its value still has to be
passed by the PHY driver.

Delete all the write only variables in CAM. At worst, the only behavior
change would be to prevent core dumps from chasing NULL pointers (though
I think in all these cases the pointers can't be NULL).
