drm/panfrost: Add Mali-G57 "Natt" support
Add the features, issues, and GPU ID for Mali-G57, a first-generation Valhall GPU. Other first- and second-generation Valhall GPUs should be similar. v2: Split out issue list for r0p0 from newer Natt GPUs, as TTRX_3485 was fixed in r0p1. Unfortunately, MT8192 has a r0p0, so we do need to handle TTRX_3485.
