Subject: [PATCH] arm64: dts: marvell: armada-37xx: Move PCIe max-link-speed
 property
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Move the max-link-speed property of the PCIe node from board specific
device tree files to the generic armada-37xx.dtsi.

Armada 37xx supports only PCIe gen2 speed so max-link-speed property
should be in the generic armada-37xx.dtsi file.
