Merge patch series "board: ti: am33xx: Add Ethernet support for Beaglebone Green Eco"

Romain Gantois <[email protected]> says:

This is version one of my series which enables Ethernet support on the BBGE
board. This requires three main changes:

 - Describing the MAC<->PHY link and DP83867 PHY accurately in the device
   tree
 - Enabling the RGMII1 pinmux configuration
 - Enabling the DP83867 driver

These changes are all applied in patch 2.

Patch 1 enables excluding the DP83867 driver from SPL. This is done to
avoid size issues when adding the DP83867 driver to the am335x-evm
defconfig.
