firmware/ipq-wifi: Add Google Wifi board-2.bin

From a manufacturer's image (version R89-13729.57.27), with appopriate
',variant=' appended to the board names:

Naming follows existing Google projects included in upstream board-2.bin
-- GO(ogle) prefix, an underscore (_), and the project code name, all in
caps.

Note that I only tested the "gale" model; the "breeze" model is a later
revision (same marketing name) with very small hardware changes but
otherwise using the same firmware image.
