Kenneth Graunke dd508b2bed iris: Don't advertise Y-tiled modifiers for scanout buffers on Gfx8
According to isl_gfx7.c:264, the display engine does not support Y
tiled buffers prior to Skylake.  But we exposed I915_FORMAT_MOD_Y_TILED
even when querying for a list of modifiers with PIPE_BIND_SCANOUT set,
which we can't support.  That led to crashes later when we tried to
create such an image, and isl rightly denied it.

Fixes crashes in wflinfo since c03e79d783, but the bug exists before
that and it's probably worth a stable backport even without that patch.
