drm/i915: fix the transition minimums for gen9+ watermarks

Browse source

The transition minimum is 14 blocks for gens 9 and 10, and 4 blocks
for gen 11. This minimum value is supposed to be added to the
configurable trans_amount. This matches both BSpec and additional
information provided by our HW engineers.
