Actually, for mt8183 it's both. And for mt8173 it will probably be
mediatek+pvr pretty soon. Each of these SoCs (like most Arm devices)
have a separate display controller and GPU, with different drivers for
each. They'll run different tests with different xfails. So we should
figure out a way to support igt running for both devices on the one
system.

Cheers,
Daniel
