drm/i915: Store the watermark latency values in dev_priv
Rather than having to read the latency values out every time, just
store them in dev_priv.
On ILK and IVB there is a difference between some of the latency
values for different planes, so store the latency values for each
plane type separately, and apply the necesary fixups during init.
