Subject: [PATCH v3 2/3] drm/panfrost: Add support for Mali on the MT8370
 SoC

Add a compatible for the MediaTek MT8370 SoC, with an
integrated ARM Mali G57 MC2 GPU (Valhall-JM, dual core),
with the same platform data as MT8186 (one regulator, two power
domains).
Despite their different GPU architecture (making them not being
compatible), the MT8186 platform data can still be used for MT8370
because it only describes supplies, pm_domains and enablement of power
management features in the panfrost driver.
