[U-Boot] [PATCH v3 1/2] fdt: Deprecate "usbethaddr" usage in fdt_fixup_ethernet()

[Bin Meng]

In fdt_fixup_ethernet() only "usbethaddr" is handled to fix up the
first usb ethernet port MAC address. Other additional usb ethernet
ports are ignored as there is no logic to handle "usbeth%daddr".

It is suggested we should use "ethaddr" for all ethernet devices.
Hence deprecate "usbethaddr" usage in fdt_fixup_ethernet().

This actually reverts commit b1f49ab8c7bad60426b30c134ae065ef77d2dfc1
"ARM: fdt support: Add usbethaddr as an acceptable MAC".
