Subject: [PATCH 0/3] Add Mali GPU support for Mediatek MT8365 SoC

This patchset adds the support of the ARM Mali G52 MC1 GPU (Bifrost),
integrated to the Mediatek MT8365 SoC, and its enablement to the
Mediatek Genio 350-EVK board.

I've tested this patchset on a Mediatek Genio 350-EVK board,
with a kernel based on linux-next (tag: next-20250813).

The panfrost driver probed with the following messages:
```
panfrost 13040000.gpu: clock rate = 450000031
panfrost 13040000.gpu: mali-g52 id 0x7402 major 0x1 minor 0x0 status

panfrost 13040000.gpu: shader_present=0x1 l2_present=0x1
[drm] Initialized panfrost 1.4.0 for 13040000.gpu on minor 1
```

Running glmark2-es2-drm with MESA 25.2 is also OK:
