[PATCH v2 1/9] dt-bindings: Add compatible for Mali Valhall (JM)

From the kernel's perspective, (pre-CSF, "Job Manager") Valhall is more
or less compatible with Bifrost, although they differ to userspace. Add
a compatible for Valhall to the existing Bifrost bindings documentation.

As the first SoC with a Valhall GPU receiving mainline support, add a
specific compatible for the MediaTek MT8192, which instantiates a
Mali-G57.

v2: Change compatible to arm,mali-valhall-jm (Daniel Stone).
