This patch is an attempt to gather the Ethernet related bindings in one file, like it's done in the MMC and some other subsystems. It should save the trouble of documenting several properties over and over in each binding document. I have used the Embedded Power Architecture(TM) Platform Requirements (ePAPR) standard as a base for the properties description, also documenting some ad-hoc properties that have been introduced over time despite having direct analogs in ePAPR.
