The ability to describe the physical ports of Ethernet devices is useful
to describe multi-port devices, as well as to remove any ambiguity with
regard to the nature of the port.

Moreover, describing ports allows for a better description of features
that are tied to connectors, such as PoE through the PSE-PD devices.

Introduce a binding to allow describing the ports, for now with 2
attributes :

- The number of pairs, which is a quite generic property that allows
differentating between multiple similar technologies such as BaseT1
and "regular" BaseT (which usually means BaseT4).

- The media that can be used on that port, such as BaseT for Twisted
Copper, BaseC for coax copper, BaseS/L for Fiber, BaseK for backplane
ethernet, etc. This allows defining the nature of the port, and
therefore avoids the need for vendor-specific properties such as
"micrel,fiber-mode" or "ti,fiber-mode".

The port description lives in its own file, as it is intended in the
future to allow describing the ports for phy-less devices.

My bot found errors running 'make dt_binding_check' on your patch:

Those errors are unrelated to the blamed patch, the patch is about Ethernet the error is about thermal-sensors.
