All of imx*.dts* use gpu: or gpu2d:/gpu3d:/vpuvg: for the GPU label.

I see allwinner does use mali: label, but maybe it would be better to 
stay consistent with the i.MX labels ?

Also, variants of gpu: label seems more popular:

linux$ grep -hro '[a-z0-9_]\+: gpu@' arch/ | sort | uniq -c
       3 adreno_gpu: gpu@
       1 bb2d: gpu@
       1 gpu2d: gpu@
       1 gpu3d: gpu@
      80 gpu: gpu@
       4 gpu_2d: gpu@
       1 gpu_3d0: gpu@
       4 gpu_3d: gpu@
       6 gpu_mem: gpu@
       1 gpu_reserved: gpu@
       2 gpu_vg: gpu@
      17 mali: gpu@
       1 v3d: gpu@
       2 zap_shader_region: gpu@
