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.
