drm/i915/de: Remove the 2 usec fast timeout

Browse source

Currently any "slow" wait will first try a "fast" wait
with a 2 usec timeout, and then fall back to whatever
timeout was specified originally. The "slow" wait will
anyway start off with a mere 10 usec polling interval,
so basically we can only save 8 usec with the "fast" wait
(maybe a bit more given hrtimer setup costs etc.).

I don't think we really do any operations in the display
code where that kinds of 8 usec saving would be meaningful.
So just get rid of the whole "fast" wait complication and
go straight for the "slow" wait.
