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.

+Tweak MHDP driver Kconfig so it can be enabled with etnaviv
+
+The MHDP driver is needed for using HDMI on the i.MX8MQ EVK, tweak its
+Kconfig entry so that it can be enabled when using etnaviv, not just
+Vivante.

+Some further investigation is required into how to manage this upstream
