drm/i915: fixup pageflip ringbuffer commands for i8xx
commit 69d0b96c095468526009cb3104eee561c9252a84 upstream.
Add a new path for 2nd gen chips that uses the commands for i81x
chips (where public docs do exist) augmented with the plane bits
from i915. It seems to work and doesn't result in a black screen
like before.
