Subject: [PATCH v2 1/3] Revert "ARM: dts: sun7i: A20-olinuxino-lime2: Fix ethernet phy-mode"

This reverts commit 55dd7e059098ce4bd0a55c251cb78e74604abb57 as it
breaks network on my A20-olinuxino-lime2 hardware revision "K" which has
Micrel KSZ9031RNXCC-TR Gigabit PHY. Bastien has probably some previous
hardware revisions which were based on RTL8211E-VB-CG1 PHY and thus this
fix was working on his board.
