Add the DT node for the GPU core found on the i.MX8QXP.
etnaviv-gpu 53100000.gpu: model: GC7000, revision: 6214
[drm] Initialized etnaviv 1.3.0 20151214 for etnaviv on minor 0
Signed-off-by: Alexander Stein <alexander.stein@ew.tq-group.com>

Based on downstream commit [1]. I am not aware if additional
modifications are necessary in etnaviv driver though. The revision
number is slightly different to the one from imx8mp:
etnaviv-gpu 38000000.gpu: model: GC7000, revision: 6204
