drm/i915: Extract i915_cs_timestamp_{ns_to_ticks,tick_to_ns}()
Pull the code to do the CS timestamp ns<->ticks conversion into
helpers and use them all over.
The check in i915_perf_noa_delay_set() seems a bit dubious,
so we switch it to do what I assume it wanted to do all along
(ie. make sure the resulting delay in CS timestamp ticks
doesn't exceed 32bits)?
