83xx, uec: split enet_interface in two variables
There's no sensible reason to unite speed and interface type into one variable. So split this variable enet_interface into two vars: enet_interface_type, which hold the interface type and speed. Also: add the possibility for switching between 10 and 100 MBit interfaces on the fly, when running in FAST_ETH mode.
