Subject: octeontx: add support for OCTEON TX target

The Cavium OCTEON TX is an ARM 64-bit SoC leveraging CPU cores and
periperhals from the Cavium ThunderX SoC.

This initial support provides a 4.14 kernel and kernel+initramfs that is
bootable on the Gateworks Newport GW630x as well as the Cavium sff8104
reference board.
