arm64: dts: marvell: Use a SoC-specific compatible for xHCI on Armada37xx
Even if the Armada 37xx does not any specific setup, the device tree binding documentation requires to use a SoC-specific version corresponding to the platform first followed by the generic version. This patch introduce this new compatible string and updates the documentation accordingly. Signed-off-by: Gregory CLEMENT <gregory.clement@free-electrons.com>
