ARM: mvebu: add core support for Armada 39x
This commit adds the core support for Armada 39x, which is quite simple: - a new Kconfig option which selects the appropriate clock and pinctrl drivers as well as other common features (GIC, L2 cache, SMP, etc.) - a new DT_MACHINE_START which references the top-level compatible strings supported for the Marvell Armada 39x. - a new SMP enable-method. The mechanism to enable CPUs for Armada 39x appears to be the same as Armada 38x. However, we do not want to use marvell,armada-380-smp in the Device Tree, in the case of the discovery of a subtle difference in the future, which would require changing the Device Tree. And the enable-method isn't a compatible string: you can't specify several values and expect a fallback on the second string if the first one isn't supported. Therefore, we simply declare the SMP enable method "marvell,armada-390-smp" as doing the same thing as the "marvell,armada-380-smp" one.
