[PATCH v1 07/27] dt-bindings: gpu: mali-valhall-csf: Add Mali Gen5 AM compatible

[Karunika Choo]

Add the generic "arm,mali-gen5-am" compatible for Mali Gen5 AM GPU
integrations.

Mali Gen5 AM systems use the external AM_GOVERNOR block for frequency
scaling, so OPP, cooling and local GPU supply properties are not valid
for this compatible.

Add a matching example node.
