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.

From 69a99101748bb1bdb2730393ef48bc152c4d244a Mon Sep 17 00:00:00 2001

Subject: [PATCH] net: thunderx: add support for rgmii internal delay modes
The XCV_DLL_CTL is being configured with the assumption that
phy-mode is rgmii-txid (PHY_INTERFACE_MODE_RGMII_TXID) which is not always
the case.
This patch parses the phy-mode property and uses it to configure CXV_DLL_CTL
properly.

Subject: [PATCH] net: thunderx: workaround BGX TX Underflow issue
While it is not yet understood why a TX underflow can easily occur
for SGMII interfaces resulting in a TX wedge. It has been found that
disabling/re-enabling the LMAC resolves the issue.
