This patch series adds preliminary support for Mali "Valhall" GPUs into
the Panfrost kernel driver. The series has been tested on the Mali-G57
on a MediaTek MT8192 system. However, that system requires additional
MediaTek-specific patches [1] as well as core mainlining for MediaTek.
I'll post the MT8192-specific Panfrost patches soon; they depend on this
core series.

On the userspace side, pre-CSF Valhall (what is supported here) uses an
identical UABI as Bifrost. Mesa support for Valhall is being worked on
in parallel [2]. I'm hoping basic support for Valhall will be available
in Mesa 22.1.
