[RFC v3 10/18] dt-bindings: gpu: Add 'resets' property for GPU initialization

Many RISC-V boards featuring Imagination Technologies GPUs require a
reset line to be de-asserted as part of the GPU power-up sequence. To
support this, add a 'resets' property (and corresponding 'reset-names')
to the GPU device tree bindings. This ensures the GPU can be properly
initialized on these platforms.
