etnaviv-gpu 134000.gpu: MMU fault status 0x00000002 on i.XM6 Quad Plus

[Luís Mendes]

I'm afraid I cannot directly use arch/arm/boot/dts/imx6qdl-wandboard.dtsi
because there are multiple differences between Wandboard Rev. C1 and Rev.
D1.
For instance Rev. C1 has no Power Management IC (PMIC) while Rev. D1 has a
pfuze100, also has a different WiFi chip and some signals are routed to
different pins.

I will try to check the differences line by line... Yes, I would be glad to
send the resulting configuration changes upstream.
