[U-Boot] [PATCH v3 08/20] net: sun8i-emac: remove support for old binding

[Andre Przywara <andre.przywara@arm.com>]

The original DT binding used by U-Boot's sun8i-emac driver was not really
agreed upon, and deviated from the "official" binding now used by the
kernel. Since now all U-Boot users have been converted to the new
binding, we can remove support for the old DT nodes from the driver.
