In order to be able to define a property describing an array of PHY
interface modes, we need to change the current scalar
`phy-connection-type`, which lists the possible PHY interface modes, to
an array of length 1 (otherwise we would need to define the same list at
two different places).

Moreover Rob Herring says that we cannot reuse the values of a property;
we need to $ref a type.

Move the definition of possible PHY interface modes from the
`phy-connection-type` property to an array type definition
`phy-connection-type-array`, and simply reference this type in the
original property.  

Why not just extend phy-connection-type to support more than 1 entry?

Hmm, that would be even better, although it would complicate the
Russell's marvell10g patches a little if we want the code to be
backward compatible with older device trees.

I will look into this.
