[PATCH v2 0/3] Add Mali GPU support for Mediatek MT8365 SoC

[Louis-Alexis Eyraud <louisalexis.eyraud@collabora.com>]

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-20251021).

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
  0x0
panfrost 13040000.gpu: features: 00000000,00000df7, issues: 00000000,
  00000400
panfrost 13040000.gpu: Features: L2:0x07110206 Shader:0x00000003
 Tiler:0x00000209 Mem:0x1 MMU:0x00002823 AS:0xff JS:0x7
panfrost 13040000.gpu: shader_present=0x1 l2_present=0x1
[drm] Initialized panfrost 1.5.0 for 13040000.gpu on minor 0
```

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