etnaviv: Use old set of state registers for PE configuration on GC880

While the GC880 is HALTI0, it still uses the old set of state registers
for PE pipe configuration. This is another specialty of the GC880, readd
the missing handling for this GPU otherwise e.g. Qt5 cube example suffers
from rendering corruption with both eglfs and wayland backends.
