[V2 2/3] MIPS: Add Onion Omega2+ board

From: Harvey Hunt
Date: Mon Aug 21 2017 - 06:56:00 EST


The Onion Omega2+ is an MT7688A based board that has 128MB RAM and
multiple peripherals.

The MT7688A is pin compatible with the MT7628A, although the former
supports a 1T1R antenna whereas the MT7628A supports a 2R2T antenna.
