[PATCH 1/4] powerpc: document max-speed and interface-type properties

[Kim Phillips <kim.phillips@freescale.com>]

Since ucc_geth is being migrated to use the phylib, the existing
(undocumented) 'interface' property is being deprecated in favour
of unconjoined variations 'max-speed' and 'interface-type'.

max-speed is necessary for QE UEC devices that do not make that
information available through their programming model.

interface-type is now maintained one-to-one with definitions
in include/linux/phy.h.
