drm/i915: increase default latency constant (v2 w/comment)
Some i915/i945 platforms have a fairly high memory latency in certain
situations, so increase our constant a bit to avoid FIFO underruns.
The effect should be positive on other platforms as well; we'll have a
bit more insurance against a busy memory subsystem due to the extra
FIFO entries.
Fixes fdo bug #23368. Needed for 2.6.31.
