[PATCH v3 16/18] arm64: dts: imx8mm: Add GPU nodes for 2D and 3D core

According to the documents, the i.MX8M-Mini features a GC320 and a
GCNanoUltra GPU core. Etnaviv detects them as:
etnaviv-gpu 38000000.gpu: model: GC600, revision: 4653
etnaviv-gpu 38008000.gpu: model: GC520, revision: 5341
This seems to work fine more or less without any changes to the HWDB,
which still might be needed in the future to correct some features,
etc.
[lst]: Added power domains and switched clock assignments to the
new clock defines used for the composite clocks, instead of
relying on the backwards compat defines.
