[PATCH 3.19.y-ckt 015/251] net: mvneta: introduce compatible string "marvell, armada-xp-neta"

[Kamal Mostafa]

3.19.8-ckt4 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Simon Guinot <simon.guinot at sequanux.org>

[ Upstream commit f522a975a8101895a85354b9c143f41b8248e71a ]

The mvneta driver supports the Ethernet IP found in the Armada 370, XP,
380 and 385 SoCs. Since at least one more hardware feature is available
for the Armada XP SoCs then a way to identify them is needed.

This patch introduces a new compatible string "marvell,armada-xp-neta".
