Add initial device tree nodes for Cavium Thunder SoCs with support of
48 cores and gicv3. The dts file requires further changes, esp. for
pci, gicv3-its and smmu. This changes will be added later together
with the device drivers.

Hmm. I take it this platform is compliant with some level of SBSA? We
should probably have a compatible value for that so that platforms can
communicate it.

Mark, are there already plans for this?
