ucc_geth: eliminate max-speed, change interface-type to phy-connection-type

It was agreed that phy-connection-type was a better name for
the interface-type property, so this patch renames it.

Also, the max-speed property name was determined too generic,
and is therefore eliminated in favour of phy-connection-type
derivation logic.
