ucc_geth: migrate ucc_geth to phylib
migrate ucc_geth to use the common phylib code.
There are several side effects from doing this:
o deprecate 'interface' property specification present
in some old device tree source files in
favour of a split 'max-speed' and 'interface-type'
description to appropriately match definitions
in include/linux/phy.h. Note that 'interface' property
is still honoured if max-speed or interface-type
are not present (backward compatible).
o compile-time CONFIG_UGETH_HAS_GIGA is eliminated
in favour of probe time speed derivation logic.
o adjust_link streamlined to only operate on maccfg2
and upsmr.r10m, instead of reapplying static initial
values related to the interface-type.
o Addition of UEC MDIO of_platform driver requires
platform code add 'mdio' type to id list
prior to calling of_platform_bus_probe (separate patch).
o ucc_struct_init introduced to reduce ucc_geth_startup
complexity.
