Add imx8mqevk machine that uses etnaviv
To enable debugging/development of the etnaviv driver against the GC7000L GPU in the i.MX8MQ, add a "imx8mqevk" template that uses etnaviv instead of Vivante. Since there seem to be some issues with respect to GPU hangs and resulting graphical corruption, the existing "imx8mqevk-viv" template that uses Vivante has been retained for now.
