drm/radeon: Ignore RADEON_GEM_GTT_WC on Kabini

There seems to be a general problem with write-combined CPU mappings of GTT=
 on
Kabini. We previously disabled write-combined mappings of the ring buffers
again because other users reported ring test failures on Kabini with that, =
but
from this report it looks like the problem runs deeper.

This kernel patch should work around it for now.
