Subject: ARM: mvebu: fix second and third PCIe unit of Armada XP mv78260
From: Arnaud Ebalard <arno@xxxxxxxxxxxx>
commit 2163e61c92d9337e721a0d067d88ae62b52e0d3e upstream.
mv78260 flavour of Marvell Armada XP SoC has 3 PCIe units. The
two first units are both x4 and quad x1 capable. The third unit
is only x4 capable. This patch fixes mv78260 .dtsi to reflect
those capabilities.
