radeon: add AGPMode 1 quirk for RV250

commit 45171002b01b2e2ec4f991eca81ffd8430fd0aec upstream.

The Intel 82855PM host bridge / Mobility FireGL 9000 RV250 combination
in an (outdated) ThinkPad T41 needs AGPMode 1 for suspend/resume (under
KMS, that is). So add a quirk for it.

(Change R250 to RV250 in comment for preceding quirk too.)
