The imx6sl soc has gpu_2d and gpu_vg, no 3d support:

etnaviv-gpu 2200000.gpu: model: GC320, revision: 5007
etnaviv-gpu 2204000.gpu: model: GC355, revision: 1215

The IP blocks are close enough to supported hardware that they "just
work" with etnaviv and x11.

Tested by using yocto fsl community bsp built in "mainline" mode. This
patch makes x11 start up and turning on drm.debug shows that the etnaviv
driver is being used.

I don't know if such a patch requires much more testing: all it really
does is "describe the hardware".

Patch is against shawguo/imx/dt, it depends on newly accepted
commit 13211eec7b0e ("ARM: dts: imx6sl: Convert gpc to new bindings")
This is only because of the way it references the PU power domain.
