The original dwmac-sun8i DT bindings have some issue on how to handle
integrated PHY and was reverted in last RC of 4.13.
But now we have a solution so we need to get back that was reverted.

This patch restore arm64 DT about dwmac-sun8i
This reverts commit 87e1f5e8bb4b ("arm64: dts: allwinner: Revert EMAC changes")
