Subject: [PATCH v2] ARM: dts: imx6sl: Add vivante gpu nodes

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 seem to be already supported.

Changes since v1:
 * Move nodes to the end of the file, sorting by address.

Link to v1: https://lists.freedesktop.org/archives/dri-devel/2018-July/183273.html

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.

Patch is against shawguo/imx/dt, it depends on newly accepted
commit 13211eec7b0e ("ARM: dts: imx6sl: Convert gpc to new bindings")
