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 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.
