[Sasha Levin <sashal@kernel.org>]

From: Josua Mayer <josua@solid-run.com>

[ Upstream commit 9a43827e876c9a071826cc81783aa2222b020f1d ]

Layerscape MACs support 25Gbps network speed with dpmac "CAUI" mode.
Add the mappings between DPMAC_ETH_IF_* and HY_INTERFACE_MODE_*, as well
as the 25000 mac capability.

Tested on SolidRun LX2162a Clearfog, serdes 1 protocol 18.
