Add a new gpu node in mt8370.dtsi to enable support for the
ARM Mali G57 MC2 GPU (Valhall-JM) found on the MT8370 SoC, using the
Panfrost driver.
On a Mediatek Genio 510 EVK board, the panfrost driver probed with the
following message:
```

Add the support of the Mediatek MT8370 SoC, a less powerful variant of
MT8390 SoC.
Their main differences are:
- Arm Cortex-A55 cores number (4 vs 6)
- Arm Cortex-A78 core speed (2.0 GHz vs 2.2 Ghz)
- Arm Mali-G57 GPU core number (2 vs 3)
Like MT8390, MT8370 hardware register maps are identical to MT8188.
Note:
The devicetree for MT8370 SoC does not currently contain the needed
overrides to support the Mali GPU integrated into this SoC. This is
scheduled to be done with a later change.
