Markus StockhausenandRobert Marko 316f41e310 realtek: dts: convert EXTERNAL_PHY() to PHY_C22()
The Realtek target currently uses two phy macros to simplify the
device dts.

- EXTERNAL_PHY() to denote a phy attached to the SoC
- INTERNAL_PHY() to denote an internal PHY (inside the SoC)

There is no benefit doing this. The topology around a port/phy is
well defined by the port macros. They link port, phy, pcs and even
leds. The only consumer of the attribute "phy-is-integrated" is
inside the dsa driver and that is being refactored.

As a first step define a new more meaningful PHY_C22() macro that
describes a c22 capable phy. This does not need to care about the
external/internal relation. To make it even more useful for the
RTL93xx targets with multiple mdio busses give it two parameters
PHY_C22(port_number, bus_address) where

- port_number is the absolute overall unique phy number
- bus_address is the location of the phy on the bus

For RTL83xx these two parameters will usually be the same. Instead
of three steps (inventing the macro, converting the consumers and
removeing the old macor) do a one-step conversion for the existing
EXTERNAL_PHY() macro.
