Updates Ethernet PHY devicetree bindings to be more consistent with
Linux by using the standard `reg` property for the PHY address instead
of a custom `address` property. As a result, MDIO controller bindings
now require standard `#address-cells` and `#size-cells` properties.

Now that all in-tree phys are declared under their mdio bus, drop the
`mdio` property and use DT_INST_BUS to find the bus.

DTS property attributes are (by default) not required.
Explicitly specifying `required: false` is redundant.
Perhaps a warning to that effect would be useful.

This commit adds support for Ethernet PHY drivers via a PHY API.
It also includes a driver for a generic MII compliant PHY
which supports most PHYs on the market.
Separating PHY driver from the SoC specific Ethernet driver
simplifies the Ethernet driver code and enables code re-use.
Drivers for specific PHYs with more advanced features, such as
RGMII delay in PHY can be developed independent of the Ethernet
MAC driver.
