Subject: [PATCH v5 1/3] dt-bindings: gpu: mali-bifrost: Add compatible for
 MT8370 SoC

Add a compatible for the MediaTek MT8370 SoC, with an
integrated ARM Mali G57 MC2 GPU (Valhall-JM, dual core).
None of the already existing SoC specific compatibles is usable as
fallback, as those either do not match the number of cores (and number
of power domains), or are for a different GPU architecture.
