ARM: mvebu: use correct name for pcie controller

When armada-385.dtsi was sync'd from Linux the name of the node
describing the pcie controller was changed from pcie-controller to pcie.
Some of the boards that include armada-385.dtsi were missed in the
update retaining the old name. This updates the affected boards.
