drm/panfrost: Add the MT8192 GPU ID

MediaTek MT8192 has a Mali-G57 with a special GPU ID. Add its GPU ID,
but treat it as otherwise identical to a standard Mali-G57.

We do _not_ fix up the GPU ID here -- userspace needs to be aware of the
special GPU ID, in case we find functional differences between
MediaTek's implementation and the standard Mali-G57 down the line.
