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
