arm64: dts: marvell: armada-37xx: Move PCIe max-link-speed property

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 genetic armada-37xx.dtsi file.
