[PATCH v4 2/2] arm64: dts: imx95: Describe Mali G310 GPU

[Marek Vasut <marek.vasut@mailbox.org>]

The instance of the GPU populated in i.MX95 is the G310, describe this
GPU in the DT. Include dummy GPU voltage regulator and OPP tables.

V2: - Drop regulator-{always,boot}-on from fixed-gpu-reg regulator
    - Keep the GPU and GPUMIX always enabled
    - Switch from fsl, to nxp, vendor prefix
    - Fix opp_table to opp-table
    - Describe IMX95_CLK_GPUAPB as coregroup clock
    - Sort interrupts by their names to match bindings
V3: - Drop perf power domain
    - Drop reset block controller
V4: - Add RB from Frank
    - Drop the now optional GPU regulator
