exynos5420: Tighten up displayport timing loops
We were running this loop 100 times with 5 ms delays. Change it to run 500 times with 1 ms delays, which gives us the same overall timeout but lets us bail out a bit sooner -- in practice, at most, 4 ms sooner but every bit counts. Note, however, that the tighter timing does reduce opportunities for threading. There is a non-obvious set of tradeoffs on timeouts.
