Add support for the SolidRun Armada 388 Clearfog A1 board.  This board
has an Armada 388 microsom, dedicated gigabit ethernet, six switched
gigabit ethernet ports, SFP cage, two Mini-PCIe/mSATA slots, a m.2 SATA
slot, and a MikroBUS connector to allow MikroBUS modules to be added.

This DT file adds support for all board facilities with the exception
of full SFP support.
