This is the first generation Amazon Echo from 2016.
Audio support is not yet implemented.

Signed-off-by: André Hentschel <nerv@dawncrow.de>

v2: Don't disable sgx, as the previous patch changes dtsi files accordingly
v3: Include dm3725.dtsi

I have local patches for the microphone array, but cleaning that up will take some time.
Audio output seems to be even harder work...
You can find a tutorial on how to boot the Echo here:

Thanks applying both into omap-for-v5.6/dt.
