[PATCH 2/3] drm/panfrost: Add support for Mali on the MT8370 SoC

[Louis-Alexis Eyraud]

This commit adds a compatible for the MediaTek MT8370 SoC, with an
integrated ARM Mali G57 MC2 GPU (Valhall-JM, dual core), and adds
platform data using the same supplies and the same power domain lists
as MT8186 (one regulator, two power domains).
