[PATCH 2/2] drm/panfrost: Add support for Mali on the MT8188 SoC

[AngeloGioacchino Del Regno]

MediaTek MT8188 has a Mali-G57 MC3 (Valhall-JM): add a new
compatible and platform data using the same supplies and the
same power domain lists as MT8183 (one regulator, three power
domains).

I believe you also need to edit one of the conditionals below so that the
number and names of the power domains are properly constrained?
