[PATCH 9/9] arm64: dts: imx95: Describe Mali G310 GPU

[Marek Vasut]

The instance of the GPU populated in i.MX95 is the G310,
describe this GPU in the DT. Include description of the
GPUMIX block controller, which can be operated as a simple
reset. Include dummy GPU voltage regulator and OPP tables.
